For many years, I've had a local patch to do that in VC, but I recently
threw it out, deciding that it deserves to be rewritten based on the
"new" tools available currently, i.e. stash/shelve.

I haven't used Mercurial enough, but I'd do a "hg shelve" (or "hg
stash" or whatever it's called and if hg doesn't have such
a functionality, I'd do it by hand: "hg diff >shelve1.diff");
Then I'd use C-x v, diff-mode and friends to add/remove changes to get
just the changes I want to commit;
Then "hg commit";
Then "hg unshelve" or "hg unstash" or "patch -p0 <shelve1.diff";
And resolve the potential conflicts, if any.
