Always assume format_commit_item() takes an utf-8 string for
simplicity. 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. It's supposed to create an
iso8859-1 commit, but the commit content in t6006-rev-list-format.sh
is in UTF-8. Split the content out in a separate file (so its encoding
won't accidentally be converted) and convert it back to iso8859-1.
