Patch for Diffutils 2.7

[Timothy Kilbourn]

Recently when comparing files in directories, I wanted diff to ignore the
files that weren't in both directories (*.o, *~, etc) without having to
figure out and specify what those files were. The following patch adds a
command line option --ignore-new-file that will not emit any output for a
file found in one directory but not the other. In addition, if this used
in conjunction with the -N or -P options, diff will display an error
message and then exit. I have found this to be useful and think it could
be included in the next release.

Changes:
