basewiki_brokenlinks.t fails when running dpkg-buildpackage in non-English environment : it greps for an (non-)error message that is i18n'd. This of course does not happen when building in a proper chroot environment... which happens to fail as well, for other reasons, but this will be for another bug.

The `LANG=` on line 9 does not seem to do what it's supposed to, go figure.

I've never had to understand the Unix locales, so I randomly tried to replace `LANG=` in basewiki_brokenlinks.t with :

- `LANG=C` : fails
- `LANGUAGE=` : fails
- `LANGUAGE=C` : works!

> For maximum precedence it should have been LC_ALL=C. Patch coming soon to http://git.debian.org/?p=users/smcv/ikiwiki.git --[[smcv]]
