pretty: save commit encoding from logmsg_reencode if the caller needs it

The commit encoding is parsed by logmsg_reencode, there's no need for
the caller to re-parse it again. The reencoded message now has the new
encoding, not the original one. The caller would need to read commit
object again before parsing.
