man pages: formatting of entries in "SEE ALSO" section

[Bernhard Voelker]

Hi *

cat(1) and tac(1) use bold formatting for the entries in the "SEE ALSO"
section, while all other 'man/*.x' files use the regular font for that.

  GIT_PAGER= git grep -A1 'SEE ALSO' -- 'man/*.x' | grep -F '\'
  man/cat.x-\fBtac\fP(1)
  man/tac.x-\fBrev\fP(1)

man-pages(7) is silent about what style to prefer.
Many other projects use '\fB...\fP' (or '.BR'/'.B').

For the coreutils, I think we should at least be consistent.
But which way? Bold or regular?

FWIW: in my opinion, tac(1) should reference cat(1) as well.

Have a nice day,
Berny
