pretty: parse the gpg status lines rather than the output
Currently, parse_signature_lines() parses the gpg output for strings which depend on LANG so it fails to recognize good commit signatures (and thus does not fill in %G? and the like) in most locales. Make it parse the status lines from gpg instead, which are the proper machine interface. This fixes the problem described above. There is a change in behavior for "%GS" which we intentionally do not work around: "%GS" used to put quotes around the signer's uid (or rather: it inherited from the gpg user output). We output the uid without quotes now, just like author and committer names. Signed-off-by: Michael J Gruber <git@drmicha.warpmail.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
