keyword: make repo.commit use a custom commitctx wrapper

This avoids forcing the dirstate of overwritten files to normal
during a commit.

Thanks to Dan Villiom Podlaski Christiansen for the idea of a
"double wrapper", so other extensions can still wrap
repo.commitctx safely.

200 Script output follows
content-type: text/plain
content-length: 157
content-disposition: inline; filename="some \"text\".txt"

This is just some random text
that will go inside the file and take a few lines.
It is very boring to read, but computers don't
care about things like that.
