Munge patches using intptr_t to include stdint.h.

Patch changes are from Iain Morgan.  Beyond that, I have:
  omitted changing patches for line # and ~/orig nits
  used INSTALLATION_DIRS for share/doc/nedit

I sent mail to upstream about the patches.  After all, the distfile is
just about 9.5 years old, so surely they are due for at least a point
release.
