[PATCH 4/5] git-svn: Provide a default "empty commit message" so the metadata is not the header

[Alex Vandiver <alex@chmrr.net>]

git-svn adds a trailing line of metadata to the commit message.  If
the commit message would otherwise be empty, this can lead to
confusing display in `gitk` and `git log --oneline`.  Thus, provide a
no-op "(empty commit message)" message for the first line of such
messages.
