FreeBSD Port: ctags-5.8

[Mathias Monnerville]

Hello,

I know ctags 5.8 is the latest upstream stable version, but I'm aware of
some nice patches and fixes labelled as ctags-5.9 in many GNU/Linux
distros. For example, Debian
chips a ctags-5.9~svn20110310 with the following changes (from
/usr/share/doc/exuberant-ctags/changelog.Debian.gz):

exuberant-ctags (1:5.9~svn20110310-2) unstable; urgency=low

  * Add Go support, from a patch by Alexey Marinichev (closes: #634166).

exuberant-ctags (1:5.9~svn20110310-1) unstable; urgency=low

  * New upstream release snapshot (thanks, Daniel Hahler; LP: #732860).
    - Fix crash with comments inside strings in OCaml (LP: #554898).
  * Drop accepted patches:
    - debian/patches/make-match-loop.patch
    - debian/patches/php-ignore-keywords-in-comments.patch
  * For Python, disable -i so imports are not tagged by default (thanks,
    Barry Warsaw; LP: #618979).
  * Upstream uses AC_SYS_LARGEFILE now, so drop explicit
    -D_FILE_OFFSET_BITS=64 in debian/rules.
  * Fix infinite loop parsing vim commands, when a non-alphanumeric
    character other than whitespace or '-' is found before the first
    alphanumeric character after 'command' (LP: #736367).


It could be nice to also have Golang support in ctags on FreeBSD.

I would be glad to open a PR for a new devel/ctags-devel port that I would
maintain.

What do you think about it?

Kind regards,
Mathias
