progress: react more reasonably to nested progress topics
Previously, we'd reset the entire progress bar state when a topic was
completed, even if it wasn't the outermost progress topic. Now we
print the state of the next progress topic on the stack if one is left
rather than reset the progress bar.
Test that qpush cleans things up if it doesn't complete
$ echo "[extensions]" >> $HGRCPATH
$ 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
$ echo >> foo
$ hg qrefresh
$ hg qpop -a
popping bad-patch
popping patch2
popping patch1
patch queue now empty
$ python -c 'print "\xe9"' > message
$ cat .hg/patches/bad-patch >> message
$ mv message .hg/patches/bad-patch
$ hg qpush -a && echo 'qpush succeded?!'

$ rm .hg/patches/patch2
now we expect the push to fail, but it should NOT complain about patch1
