I don't think anybody asked this: why do we have both promptchoice and
promptselection?

As far as I understand, the only difference between the two is that
promptselection returns a string to the caller (like "abort", "new",
...) instead of an integer like promptchoice. There is also a nice help
in promptselection. Did I miss anything else?

TortoiseHg already works with promptchoice: I believe they have a custon
ui subclass that makes it do the right thing, namely pop up a GUI dialog
with the choices.

If we add promptselection, then they'll have to override that too in
their subclass and basically make it do what promptchoice does. If we
just change promptchoice, then they'll have to change their code
accordingly.
