qfold: allow to specify '--message/'--logfile' and '--edit' at the same time
Before this patch, 'hg qfold' disallows to specify
'--message/'--logfile' and '--edit' at the same time.
'hg qfold' has disallowed such combination since Mercurial 0.9.2, but
this restriction seems not to be reasonable for recent Mercurial,
because all other commands creating new changeset allow it.
This patch allows 'hg qfold' to specify '--message/'--logfile' and
'--edit' at the same time like other commands creating new changeset.
