That'll be interesting to track.  I do something probably similar to you: I
diff inside Emacs but always $vcs commit from a shell.  I vaguely remember
some ancient way of doing tree-based commits using svn in Emacs, but those
brain cells have long been recycled.

One thing I miss so far with Mercurial is 'smerge' mode.  When I have a
conflict in a Bazaar branch, I can just visit the conflicting file and Emacs
dumps me in a minor mode called smerge.  This gives me key bindings to hop
around between conflict areas, select which part I want (or both) and then
automatically calls $vcs resolve when all the conflict areas are taken care
of.  Makes it *very* nice for dealing with such things, but in the one case I
tried it with Mercurial conflicts, it didn't work.  I'll have to investigate
further, but I'm guessing it's caused by some incompatibility with hg's
conflict markers.

In case you missed it, there are now *three* Python modes.  Tim Peters'
original and best (in my completely unbiased opinion <wink>) python-mode.el
which is still being developed, the older but apparently removed from Emacs
python.el and the 'new' (so I've heard) python.el.

Since Skip and I work on python-mode.el, you can tell what our preference is.
The fact that it hasn't been pulled into Emacs is a long and dark political
tale full of intrigue, subterfuge, fast cars, Matt Damon, sharks with frickin'
laser beams attached to their heads, and downright redonkulousness.  If you
want the full gory details (or just want to help make the most awesome Python
editing mode even awesomer), come join us on python-mode at python.org.
