[Bugfix] Fix DWAINE grep -o printing empty lines

[NinjaKyat]

Currently the -o (print match only) option for DWAINE's grep command does not work as intended. Instead of the matching text it only prints an empty line, making it a bit less useful.

This simple one line fix resolves the issue. (Calling grep -o will now return the match only, without the filename or line numbers).

I've made a pull request, but it also involves applying the original grep patch.


Here's the Patch.
