[pdf.tmac]: Fix problem with hotspot placement.
* tmac/pdf.tmac (pdf*href): Fix problem with hotspot placement when
there is no link text (illustrated by the "See also" section of pic(1)
when rendered to PDF). It is apparently necessary to flush the output
buffer immediately after constructing certain device control nodes
("pdf: markstart" and "pdf: markend" in this case). Deri understands
this stuff better than I do; the misapprehensions I exhibited in
Savannah #65052 might be related. If that's the case, then the issue
is maintaining synchrony between the formatter's idea of the drawing
position and the output driver's.
