You're right! It works for me with both evince (my usual viewer) and
xpdf as it does for you. I had had a problem with PDF man pages in the
past but couldn't remember clearly what it was, and had thought it was
this.
But I was able to copy-and-paste and run the "ls -l" from the attached
trivial man page from the PDF without trouble:
$ groff -Tpdf -man hyphen-minus.man > hm.pdf
$ evince hm.pdf
This is actually a relief to me. I feared that special-casing the \-
would become a camel's nose that would support the recent lobbying
effort for permanent degradation of traditional *roff glyphs to ASCII
"just for man pages".
