ui: split the `default` arg out of **kwargs for the internal prompt method

This arg was required anyway, based on how it was accessed.  Having it separate
allows it to be typed though, and this will simplify things for the callers- if
a non-None `default` is passed, the return can never be None.  That can be
expressed with `@overload` when the arg can be typed, but that's not possible
when it is rolled up in **kwargs.

The default value is simply copied from the public `prompt()` above it.

Bookmark is usually an indication of a head. For changes that are introduced by
an ancestor of bookmark B, after moving B to B-NEW, the changes are ideally
still introduced by an ancestor of changeset on B-NEW. In the below case,
"BOOK-D", and "BOOK-E" include changes introduced by "C".

Previously, there was a bug where the empty commit check compared the parent
branch name with the wdir branch name instead of the actual branch name (which
should stay unchanged if --keepbranches is passed), and erroneously assumed
that an otherwise empty changeset should be created because of the incorrectly
assumed branch name change.
