[Quilt-dev] [PATCH] push: Fix handling of "quilt push 0"

[Jean Delvare]

"quilt push 0" returns the following cryptic message:
Now at patch patches/quilt

So add the same check we already have in command pop and detect when
nothing needs to be done, returning the more sane message:
No patch applied
