I don't think this kind of change is appropriate.  Feature branches
should not add/remove features not directly related to the feature
being developed on the branch.  If we want to remove
redisplay-dont-pause from Emacs (and I'm not yet sure we do), it
should be discussed on emacs-devel or in a dedicated bug report, not
silently installed on the branch.

So I think this changeset should be reverted from the branch.  If you
found that this variable somehow adversely affects child frames on
tty, let's discuss what you found and the possible solutions.

Thanks.
