Jake suggested using "x false" instead of "edit" for some corner cases.
I do prefer using "x false" for all kinds of things such as stopping
before a commit (edit only let's you stop after a commit), and the
knowledge that "x false" does the least amount of actions behind my back.

We should have that command as well, maybe?



I agree. I use "x false" very often, and I think stop is probably a
better solution since it avoids spawning an extra shell that will just
fail. Not sure if stop implies too much about "stop the whole thing"
as opposed to "stop here and let me do something manual", but I think
it's clear enough.

'hold' or 'pause' maybe options (leads to 
http://www.thesaurus.com/browse/put+on+hold offering procastinate etc.)
'adjourn'.
