It's merely a recommendation. I don't want to cover every single use
case because that would be insane. I'm already worried I've covered too
many cases for people to read it all.

Tags don't appear on 'git log --oneline' or cgit/gitweb shortlog. If you
are groking through multiple bugs, it is more convenient if you can find
the bug no straight away.

'Fixes' is the original tag used by other projects. 'Bug' is shorter
than 'Gentoo-bug' and avoids repeating the obvious. Much like we do not
have 'Gentoo-signed-off-by', 'Gentoo-thanks-to' and so on, having
'Gentoo-bug' is equally silly.
Furthermore, full URLs should be used with tags. If you are already
using tags (i.e. long form), don't do it half-way and put useless digits
there. Put URL that will be interpreted by practically all visual git
tools written ever.

Yes, thanks.

I'm not stopping anyone. This is merely a suggestion. Encouraging two
different tags for the same thing would be confusing to users.
