Hello,

it would be nice if filterdiff had an option to exclude files where
one of the changes to the file matches a pattern.

Use case: When comparing two releases of a software I like to exclude
autogenerated files. For autoconf/automake filename patterns work
reasonably well however the output of GNU autogen cannot be filtered
this way. Something like this would work:

filterdiff --exclude-files-changes ' It has been AutoGen-ed '

part of example diff:
-----------------------------------------------------
diff -Nru autogen-5.16/autoopts/autoopts/options.h autogen-5.16.2~pre9/autoopts/autoopts/options.h
--- autogen-5.16/autoopts/autoopts/options.h    2012-05-07 01:21:03.000000000 +0200
+++ autogen-5.16.2~pre9/autoopts/autoopts/options.h     2012-08-09 17:50:36.000000000 +0200

This can be achieved by using grepdiff together with filterdiff, e.g:
 
$ grepdiff ' It has been AutoGen-ed ' my.patch | filterdiff -X /dev/stdin my.patch
 
See the manpage of grepdiff for a similar example.

That looks like a perfect solution. Thanks.
