Re: [PATCH 12/12] t3901: test git-am encoding conversion

> Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am
> supported the --utf8 and --no-utf8 options, and if set, would pass the
> -u flag and the -k flag respectively.
>
> git mailinfo -u will re-code the commit log message and authorship info
> in the charset specified by i18n.commitencoding setting, while
> git mailinfo -n will disable the re-coding.
>
> Since d84029b (--utf8 is now default for 'git-am', 2007-01-08), --utf8
> is set by default in git-am.
>
> Add various encoding conversion tests to t3901 to test git-mailinfo's
> encoding conversion. In addition, add a test for --no-utf8 to check that
> no encoding conversion will occur if that option is set.
