The goal as I understand it is to create a branch which stores my
partially completed WC work so I can go work on something else. This is
very much like a commit, so logically I would want to choose which
changed and unversioned files are going to get included. So...

Add a 4th branch mechanism to the branch/tag dialog:
( ) Head revision
( ) Specific revision
( ) Working copy
(*) Shelf (WC base + changes) // Dodgy description

Start up a dialog which looks a lot like Commit. This does an svn
status, so it knows whether I have a mixed revision working copy. If
that is the case, simply abort and explain that the shelf must be based
on a clean single-revision WC. Explaining that succinctly in a dialog
may be the hardest part of the exercise ;-)

Having done that check, we know which single revision the WC is based
on, so do a repository copy of that rev to the branch. The log message
here comes from the branch/tag dialog.

Then switch to the branch and commit the marked files. There may be a
technical reason why this is not easy after the switch has happened. The
second log message comes from the commit-style dialog.

This sounds like a non-trivial feature request, with a limited audience,
and I wonder whether there is enough call for it to justify that amount
of work. Although it is a bit easier than doing all the component parts,
there are still a few dialogs to click through. All it is doing is
guiding you rather than saving much work.

There is already a feature request to make CreatePatch use a commit
dialog style front end. I don't know how much common code there would be
if that is done. Possibly not much.
