stack: make a deep copy of `dependencies` before modifying its items
The algorithm later on in this method uses .remove() to remove individual
elements from items in dependencies, which before this patch modified the
cached property contents. So for further use that dictionary was in the form of
{1: set([])}, i.e. all sets were empty.
This deep copy block could be way simpler, but the problem is that sometimes we
get lists of _succs() from evolvebits.builddependencies(). Note: this happens
only in topic's stack version of builddependencies() and it looks like a
suboptimal way to handle multiple successors (see evolve's counterpart
function).
stack.builddependencies method is removed, it has served its purpose (see the
previous patch).
Testing the `--no-update` flag to `hg evolve` command
=====================================================
There is an `--update` flag to `hg evolve` command which defaults to False. The
`--update` flag updates to the head of the evolved revisions. If you don't want
to change your working directory or update your working directory to its
successor after hg evolve, `hg evolve --no-update` is the thing for you.
This patch tests that flag.
