Always assume format_commit_item() takes an utf-8 string for string handling simplicity (we can handle utf-8 strings, but can't with other encodings).
If commit message is in non-utf8, or output encoding is not, then the commit is first converted to utf-8, processed, then output converted to output encoding. This of course only works with encodings that are compatible with Unicode.
This also fixes the iso8859-1 test in t6006. It's supposed to create an iso8859-1 commit, but the commit content in t6006 is in UTF-8. t6006 is now converted back in UTF-8 (the downside is we can't put utf-8 strings there anymore).
