uncomment region bug

Uncomment-region lops off a couple characters when the region is flush
against the end of the buffer.

  1. Make an Emacs Lisp Mode buffer containing just  ;; foo[EOB]
  2. M-<
  3. C-SPC
  4. M->
  5. M-x uncomment-region

Result:

  f[EOB]

The function `comment-enter-backward' seems to be doing some very
strange things here; too strange for me to understand.
