Since no one seemed to object and it's a trivial change, here's a
patch to add ?\_ support. Light testing here shows no ill effects.

The patch does the following:

1. Adds support for ?\_ to lread.c,
2. Documents ?\_ in lispref,
3. Augments checkdoc to replace end-of-line `? ' and `?\ ' with `?\_',
   (Note that this change isn't as good as it could be, but I don't
    know anything about checkdoc's internals.)
4. Updates etc/NEWS and the various ChangeLogs (which presumably
   should be changed by whoever checks this in).

I hope this change squeaks in under the paperwork threshold (it's
really very very simple), but if not, I'm perfectly willing to
sign papers.
