Arch Linux

Description:
LESS_TERMCAP variables are not correctly followed as of groff 1.22.2

Additional info:
* package version(s)
groff 1.22.2-1
less 451-1

* config and/or log files etc.
LESS_TERMCAPS I am using: http://ix.io/4jz

Steps to reproduce:
This sounds like it's only reproducable with a UTF-8 locale.
1) upgrade groff to 1.22.2-1 in [testing]
2) source the file linked above in a shell
3) run `man man`
Note the colors are distinctly lacking.
4) now install core/groff (version 1.21-2 at this writing)
5) source the file linked above in a shell
6) run `man man`
Note that there are colors.

* possible cause
I pulled the packages/groff branch from the core/extra git repository, and looked through the diff. The `site.tmac` file was removed from the 1.22.2-1 PKGBUILD and adding this back corrects this bug. I don't know what exactly this is going, but it seems that UTF-8 man page processing isn't completely right yet.
