Any kind of shell history has that feature (or problem, depending on
your point of view). I think it's a reasonable compromise.

Right, so the history would be per repository and the very first initial
guess would be "git push" usually?  I would use that.

Unless there's a strong protest, I can try implementing a first cut of
this. I like that it fills a void, where you say "DWIM" after a Git
commit and VC goes "huh? go away!" :)

That's unfortunate.  I use both, but VC is definitely more convenient
for "smaller" interactions.  Magit tends to be an all-day workflow.
