A new alpha release is available here:

https://alpha.gnu.org/gnu/patch/patch-2.7.6.211-86ac.tar.gz
https://alpha.gnu.org/gnu/patch/patch-2.7.6.211-86ac.tar.bz2
https://alpha.gnu.org/gnu/patch/patch-2.7.6.211-86ac.tar.xz

Major changes since Jim's snapshot:

* Reject newlines when creating new files, but not when
  accessing existing files.
* Some test suite compatibility fixes.

Pending any last-minute glitches, this should be the final pre-release snapshot.

Thanks for all your help!
