histedit: resolve revs before evaluating %ld revset
We want to stop relying on basectx.__int__. That means we can't
use the %ld revset operator with an iterable of contexts. So
we expand an iterable of contexts into a list of revs before calling
into the revset.
Perhaps it would be worthwhile to add a revset format operator
that recognizes context instances so we can just pass contexts
as revset arguments?

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
