Subject: commit-tree: cope with different ways "utf-8" can be spelled.
X-Git-Tag: v1.5.0-rc1~147
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=677cfed56ac530878b746ee4cca3ada8af384a81;p=git.git

commit-tree: cope with different ways "utf-8" can be spelled.

People can spell config.commitencoding differently from what we
internally have ("utf-8") to mean UTF-8.  Try to accept them and
treat them equally.
