By committing changes of this sort to base-config and languagechooser at
this point *without testing them*, you run the risk of getting a nice
errata item for your language for the final sarge release that says
"does not work, pick another language". It's stupid, don't do it.
Also, NEVER commit code changes to base-config at this point without
talking to me. I have to explain each code change in base-config to the
release managers; which is impossible if nobody has explained them to
me. People who abuse this privelige will lose commit access to
base-config.
(BTW, the branch of base-config you committed your changes to is not one
that will ever be released in sarge, so I assume you just broke your
language by getting languagechooser and base-config out of sync. One
reason you should talk to the maintainer first.)
(Also BTW, you documented your change in the changelog entry for a
released version of base-config, which is broken and indicates you don't
know what you're doing even if none of the above did.)
