O. emacs -Q
1. Open a man page that has a link on a hyphenated word, e.g. on my
system: M-x man RET signal RET, put point on the word spanning lines
129-130, which is displayed as `sig-
nalfd(2)'.
2. Type RET (or click mouse-1 or mouse-2) on that link.
=> The error message "Can’t find the 2 sig-nalfd manpage" is displayed.
The following patch makes the link DTRT:
diff --git a/lisp/man.el b/lisp/man.el

This is a long-standing bug (presumably since commit
162a12b1d7b1e985a8810bad24d068c825286f56 of Sep 13 2007), but although
the fix seems safe, I suppose it's too late for emacs-25. So if there
are no objections, should I commit it to master, or is it ok for the
upcoming release?
