[Diffutils-devel] expand exclude flag to allow for paths instead of just file names

[J-]

Hey Guys  would it be possible to modify the exclude code so that we could 
exclude (-x) full paths?

currently i can only do this (filename level) "-x banner.txt"

but i only want to exclude if banner.txt is in folder "-x 
*/resources/banner.txt"

I know i can grep this, but the output of brief doesn't show the full path, of 
the files.

ie: "Only in /Projects/src/main/resources: banner.txt"

Patch would be simple, but is there a better way?
