I'm afraid of duplication:

find -not -name "*.py" -executable | xargs grep -l mpm | xargs hg st
-mn | xargs hg ci

And here I'd add a flag to status to add/exclude subrepo files to do
hg st --nosubrepo | xargs hg ci


Or are we only targetting users that do not have "proper" shells and
toolchains? *cough* *cough*?


In reality, I feel that it would take us away from the "There should
be one-- and preferably only one --obvious way to do it." Zen, but if
you can do this without affecting other parts of Mercurial, I won't
mind.
