[PATCH 0 of 2] grep: fix -r on symlink to dir

[Thomas De Schampheleire]

This small series fixes 'grep -r' on a symlink to a directory: grep should
recurse in the symlinked directory.

As noted on the first patch, I split the test from the fix for easier
verification, but if you prefer I can fold both together.
