Are you using "C-x v v", perhaps?  At some point in the past I
proposed to teach "C-x v v" to suggest a push after commit, or even
optionally do a push without asking, given some user customization.
But that idea was shot down for reasons I still don't understand.
I think keeping push out of the "C-x v v" cycle makes that command
much less useful nowadays.
