Revision 4b46e22d48271d1a220133a925dc5009048eb577 authored by Junio C Hamano on 30 December 2006, 10:18:24 UTC, committed by Junio C Hamano on 30 December 2006, 10:18:24 UTC 
commit re-encoding: fix confusion between no and default conversion.
 
Telling the git-log family not to do any character conversion is
done with --encoding=none, which sets log_output_encoding to an
empty string.  However, logmsg_reencode() confused this with
log_output_encoding and commit_encoding set to NULL.  The latter
means we should use the default encoding (i.e. utf-8).
