Test that qpush cleans things up if it doesn't complete

$ echo "mq=" >> $HGRCPATH
$ hg init repo
$ cd repo
$ echo foo > foo
$ hg ci -Am 'add foo'
adding foo
$ touch untracked-file
$ echo 'syntax: glob' > .hgignore
$ echo '.hgignore' >> .hgignore
$ hg qinit
test qpush on empty series
$ hg qpush
no patches in series
$ hg qnew patch1
$ echo >> foo
$ hg qrefresh -m 'patch 1'
$ hg qnew patch2
$ echo bar > bar
$ hg add bar
$ hg qrefresh -m 'patch 2'
$ hg qnew --config 'mq.plain=true' bad-patch
