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.

posix: workaround lack of TIOCGWINSZ on Irix (issue3449) On an Irix 6.5.24 system, TIOCGWINSZ is not available. This means that any usage of the "hg" tool that looks up the terminal size (e.g. "hg help") will fail with an AttributeError. A simple work-around is just to wrap this block in mercurial/posix.py with a try/except so that it ends up using the default 80 characters width.
