This is a scripted change:

$ mkdir man/;
$ mv man* man/;
$ ln -st . man/man*;
$ find share/mk/ -type f \
	| xargs grep -l '^MANDIR *:=' \
	| xargs sed -i '/^MANDIR *:=/s,$,/man,';
$ find share/mk/dist/ -type f \
	| xargs grep -l man \

-.SH DESCRIPTION
-These functions serve to extend and/or modify the behavior of the
-.BR printf (3)
-family of functions.
-.SS register_printf_specifier()
-This function registers a custom conversion specifier for the
-.BR printf (3)
-family of functions.
-.TP
-.I spec
-The character which will be used as a conversion specifier in the format string.
-.TP
-.I func
-Callback function that will be executed by the
-.BR printf (3)
-family of functions
-to format the input arguments into the output
-.IR stream .
-.RS
-.TP
-.I stream
-Output stream where the formatted output should be printed.
-This stream transparently represents the output,
-even in the case of functions that write to a string.
-.TP
-.I info
-Structure that holds context information,
-including the modifiers specified in the format string.
-This holds the same contents as in
-.IR arginfo .
-.TP
-.I args
-Array of pointers to the arguments to the
-.BR printf (3)\c
--like function.
-.RE
-.TP
-.I arginfo
-Callback function that will be executed by the
-.BR printf (3)
-family of functions
-to know how many arguments should be parsed for the custom specifier
-and also their types.
-.RS
-.TP
-.I info
-Structure that holds context information,
-including the modifiers specified in the format string.
-This holds the same contents as in
-.IR func .
-.TP
-.I n
-Number of arguments remaining to be parsed.
-.TP
-.I argtypes
-This array should be set to
-define the type of each of the arguments that will be parsed.
-Each element in the array represents one of the arguments to be parsed,
-in the same order that they are passed to the
-.BR printf (3)\c
--like function.
-Each element should be set to a base type
-.RB ( PA_ *)
-from the enum above,
-or a custom one,
-and optionally ORed with an appropriate length modifier
-.RB ( PA_FLAG_ *).
-.RS
-.P
-The type is determined by using one of the following constants:
-.TP
-.B PA_INT
-.IR int .
-.TP
-.B PA_CHAR
-.IR int ,
-cast to
-.IR char .
-.TP
-.B PA_WCHAR
-.IR wchar_t .
-.TP
-.B PA_STRING
-.IR "const char\~*" ,
-a \(aq\e0\(aq-terminated string.
-.TP
-.B PA_WSTRING
-.IR "const wchar_t\~*" ,
-a wide character L\(aq\e0\(aq-terminated string.
-.TP
-.B PA_POINTER
-.IR void\~* .
-.TP
-.B PA_FLOAT
-.IR float .
-.TP
-.B PA_DOUBLE
-.IR double .
-.TP
-.B PA_LAST
-TODO.
-.RE
-.TP
-.I size
-For user-defined types,
-the size of the type (in bytes) should also be specified through this array.
-Otherwise, leave it unused.
-.RE
-.P
-.I arginfo
-is called before
-.IR func ,
-and prepares some information needed to call
-.IR func .
-.SS register_printf_modifier()
-TODO
-.SS register_printf_type()
-TODO
-.SH RETURN VALUE
-.BR \%register_printf_specifier (),
-.BR \%register_printf_modifier (),
-and
-.BR \%register_printf_type ()
-return zero on success, or \-1 on error.
-.SS Callbacks
-The callback of type
-.I printf_function
-should return the number of characters written,
-or \-1 on error.
-.P
-The callback of type
-.I \%printf_arginfo_size_function
-should return the number of arguments to be parsed by this specifier.
-It also passes information about the type of those arguments
-to the caller through
-.IR argtypes .
-On error, it should return \-1.
-.SH ERRORS
-.TP
-.B EINVAL
-The specifier was not a valid character.
-.SH STANDARDS
-GNU.
-.SH HISTORY
-.BR \%register_printf_function (3)
-is an older function similar to
-.BR \%register_printf_specifier (),
-and is now deprecated.
-That function can't handle user-defined types.
-.P
-.BR \%register_printf_specifier ()
-supersedes
-.BR \%register_printf_function (3).
-.SH EXAMPLES
-The following example program registers the 'b' and 'B' specifiers
-to print integers in binary format,
-mirroring rules for other unsigned conversion specifiers like 'x' and 'u'.
-This can be used to print in binary prior to C23.

-.SH DESCRIPTION
-A few programs exit with the following error codes.
-.P
-The successful exit is always indicated by a status of
-.BR 0 ,
-or
-.B EX_OK
-(equivalent to
-.B EXIT_SUCCESS
-from
-.IR <stdlib.h> ).
-Error numbers begin at
-.B EX__BASE
-to reduce the possibility of clashing with other exit statuses
-that random programs may already return.
-The meaning of the code is approximately as follows:
-.TP
-.B EX_USAGE
-The command was used incorrectly,
-e.g.,
-with the wrong number of arguments,
-a bad flag,
-bad syntax in a parameter,
-or whatever.
-.TP
-.B EX_DATAERR
-The input data was incorrect in some way.
-This should only be used for user's data and not system files.
-.TP
-.B EX_NOINPUT
-An input file (not a system file) did not exist or was not readable.
-This could also include errors like "No message" to a mailer
-(if it cared to catch it).
-.TP
-.B EX_NOUSER
-The user specified did not exist.
-This might be used for mail addresses or remote logins.
-.TP
-.B EX_NOHOST
-The host specified did not exist.
-This is used in mail addresses or network requests.
-.TP
-.B EX_UNAVAILABLE
-A service is unavailable.
-This can occur if a support program or file does not exist.
-This can also be used as a catch-all message
-when something you wanted to do doesn't work, but you don't know why.
-.TP
-.B EX_SOFTWARE
-An internal software error has been detected.
-This should be limited to non-operating system related errors if possible.
-.TP
-.B EX_OSERR
-An operating system error has been detected.
-This is intended to be used for such things as
-"cannot fork",
-"cannot create pipe",
-or the like.
-It includes things like
-.BR getuid (2)
-returning a user that does not exist in the
-.BR passwd (5)
-file.
-.TP
-.B EX_OSFILE
-Some system file
-(e.g.,
-.IR /etc/passwd ,
-.IR /etc/utmp ,
-etc.)
-does not exist,
-cannot be opened,
-or has some sort of error (e.g., syntax error).
-.TP
-.B EX_CANTCREAT
-A (user specified) output file cannot be created.
-.TP
-.B EX_IOERR
-An error occurred while doing I/O on some file.
-.TP
-.B EX_TEMPFAIL
-Temporary failure,
-indicating something that is not really an error.
-For example that a mailer could not create a connection,
-and the request should be reattempted later.
-.TP
-.B EX_PROTOCOL
-The remote system returned something that
-was "not possible" during a protocol exchange.
-.TP
-.B EX_OSFILE
-You did not have sufficient permission to perform the operation.
-This is not intended for file system problems,
-which should use
-.B EX_NOINPUT
-or
-.BR EX_CANTCREAT ,
-but rather for higher level permissions.
-.TP
-.B EX_CONFIG
-Something was found in an unconfigured or misconfigured state.
-.P
-The numerical values corresponding to the symbolical ones
-are given in parenthesis for easy reference.
-.SH STANDARDS
-BSD.
-.SH HISTORY
-The
-.I <sysexits.h>
-file appeared in 4.0BSD for use by the deliverymail utility,
-later renamed to
-.BR sendmail (8).
-.SH CAVEATS
-The choice of an appropriate exit value is often ambiguous.
