Subject: [PATCH (GIT-GUI BUG)] git-gui: Fix post-commit status with subject in non-locale encoding.
Message-ID: <200901240018.13457.angavrilov@gmail.com>
URL: https://gitlist.dev/e/200901240018.13457.angavrilov%40gmail.com

```
As pointed out in msysgit bug #181, when a non-locale encoding
is used for commits, post-commit status messages display the
subject incorrectly. It happens because the file handle is
not properly configured before the subject is read back.

This patch fixes it by factoring out the code that is
used to setup the output handle into a separate function,
and calling it from the reading code.
