mq: qpop now tells which patches are popped
When navigating through a patch series by qpushing and qpopping it was easy to
get lost because qpop was silent. I found myself often running qnext after qpop
to see which patch I just dropped - especially if I was about to qrm it. This
patch makes qpop more symmetric to qpush by showing which patches are
applied/"unapplied".
I think it is a good change even though it changes output by adding a new line
of output.
% inserve
A dir/c
? a
? dir/b
? hg.pid
% moving dir out
% status
! dir/c
? a
? hg.pid
Are we able to kill the service? if not, the service died on some error
