[RFC/PATCH] git-shortlog: respect i18n.logOutputEncoding config setting

[Miklos Vajna <vmiklos@frugalware.org>]

As git-shortlog can be used as a filter as well, we do not really have
the encoding info to do a reencode_string(), but in case
i18n.logOutputEncoding is set, we can try to convert to the given value
from utf-8.

It was just annoying for me that git log respected
i18n.logOutputEncoding, but I still saw unencoded utf-8 in git-shortlog
output. This patches fixes my problem.

Yes, I'm aware that hardwiring that utf-8 value is a bit hackish. But at
least this way the output encoding is correct in case the original
encoding is utf-8, which is true in most cases.

Or do you have a better idea?
