Wow, what a gold mine... I tested eshell a long long time ago,
thought the idea was interesting but... stopped there.

Re-trying with a more recent version changed the game.

Finally, after all this years, I will be able to use a *working*
shell on windows (when I need to go there).

Thanks a lot for that.

By the way, eshell delegate to term for that particular problem
so you were perfectly right for the directions.

I went an even simpler route:

(require 'eshell)
(global-set-key "\C-z" 'eshell)
(setq eshell-visual-commands (cons "bzr-shelve" eshell-visual-commands))

bzr-shelve being:

./bzr shelve

And that works perfectly fine.

So let's forget about my fears for emacs support.

I now think that this new shelf should be plugged directly into
diff-mode anyway which is a totally different approach (where all
the chunks are already displayed in an emacs buffer and some
key bindings should be added there to drive the shelves).

The actual implementation of bzr shelve is perfectly fine with
eshell and eshell being included in emacs batteries and needing
only the small tweaks described above sounds adequate to begin

That's one more incentive to look at some emacs + pymacs + bzr
combo... that itches me more and more...
