pick: don't create any successors when there were no changes (issue6093)
For example, when a changeset that user is trying to pick was already grafted
or rebased (and no obsmarkers were created), pick will naturally say that
there's no changes to commit and will not create the new commit. In that case
it should not mark any changeset as a successor of the picked changeset,
because the actual file changes were already there before picking.
Technically, pick could (and did before this patch) mark the wdir commit as a
successor of picked changeset (may be useful in the most trivial cases when
e.g. wdir is a graft of the required change), but there are cases when the
picked change is introduced in an ancestor of wdir, or even in multiple
ancestors piece by piece. Pick definitely shouldn't be trying to guess
something this complicated, so with this patch it always marks the picked
change as pruned if it gave no changes to commit.
Tests for the --stop flag for `hg evolve` command while resolving orphans
=========================================================================
The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on
This is testing cases when `hg evolve` command is doing orphan resolution.
Setup
=====
$ cat >> $HGRCPATH <<EOF

> glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
> [extensions]
> EOF
$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
$ hg init stoprepo
$ cd stoprepo
$ echo ".*\.orig" > .hgignore
$ hg add .hgignore
$ hg ci -m "added hgignore"
$ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;

Testing `--stop` when no evolve is interrupted
==============================================
$ hg evolve --stop
abort: no interrupted evolve to stop
[255]
Testing with wrong combinations of flags
========================================
$ hg evolve --stop --rev 1
abort: cannot specify both "--rev" and "--stop"
[255]
$ hg evolve --stop --continue
abort: cannot specify both "--stop" and "--continue"
[255]
$ hg evolve --stop --all
abort: cannot specify both "--all" and "--stop"
[255]
$ hg evolve --stop --any
abort: cannot specify both "--any" and "--stop"
[255]
Testing when only one revision is to evolve
