Subject: bug#8216: 24.0.50; Emacs hangs when pressing C-_ in calc

In the trunk version (tested here with revision 103577), pressing C-_
in the *Calculator* buffer results in calc-missing-key being called
forever, with 100% CPU usage.

Reproduce with:
   $ emacs -Q
   C-x * * C-_

The bug doesn't occur in the emacs-23 branch.
