mq: rename --check into --keep-changes
I named it --check because it felt like qpush & co were checking *more*
things to ensure local changes could not be lost. But it has been
pointed on the mailing list that --check is already used by update
command with a meaning almost opposite to this one. An alternative
was --keep but qfold and qdelete already have such an option to preserve
patch files and qfold may be a candidate for --check.
- qpush/qpop/qgoto --check becomes --keep-changes.
- mq.check becomes mq.keepchanges.
- The short option -c is dropped as -k may conflict with existing
--keep. The availabilitity of mq.keepchanges should not make this too
painful.
- Fix minor reST mistake in option description.
