[darcs-users] Return a failure error code on quitting with "q"

[Ganesh Sittampalam]

Hi Ash,

My gut feeling is that it makes sense to have the non-zero code.

I'm not so sure whether it makes as much sense from things like "darcs
changes -i" where quitting is pretty much expected, but overall I'd be
inclined to think it's better to be consistent than to do it command by
command.

I can't find any "well-known" error code to indicate "user asked to
abort" at http://stackoverflow.com/a/1535733/96982 - I suppose it would
be better to distinguish the case from other kinds of failure though.

Cheers,

Ganesh

I have another script I run to push both the darcs and git changes to their respective remote locations. The slight problem is that if I realise I've made a mistake, and abandon the darcs push by typing "q", darcs exits with a status code 0, so my script has no way to know I want to abort the whole process.
