It wouldn't be hard to convert at some point between the editor and the
commit object, and you don't re-edit the commit objects like you do
tracked files. It probably wouldn't even be hard for commit-tree to
convert its input based on locale. (And stuff which prints commit contents
for user consumption probably ought to re-encode it if necessary, too)
Don't get me wrong. I am not opposed to giving preferential
treatment to UTF-8 by supporting it better. I think it may be a
good idea to have an *option* in commit-tree and mktag to
convert from LC_CTYPE to utf-8, just like mailinfo does.
I am just opposing to make UTF-8 mandatory.
