[bug-grep] Fixes to 'Grep' entry in FSF/UNESCO Directory

[Julian Foad]

Please could the directory maintainer make the following two corrections to the 
entry for GNU Grep as seen at http://directory.fsf.org/grep.html

1. Support contacts: Bug List: change from "address@hidden" to 
"address@hidden".

2. Related information: Related programs: change from "Diffutils, Diffutils, 
wdiff, Findutils" to "Diffutils, wdiff, Findutils" (removing a duplicate entry).

Thanks,

- Julian
