Subject: Set default diff output format after parsing command line
X-Git-Tag: v1.4.2-rc1~85^2~16
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c9b5ef998a3027d9f11b0820bb13896096833ccb;p=git.git

Set default diff output format after parsing command line

Initialize output_format to 0 instead of DIFF_FORMAT_RAW so that we can see
later if any command line options changed it.  Default value is set only if
output format was not specified.
