[PATCH 2 of 2] grep: -r should recurse into symlinks to directories

[Thomas De Schampheleire]

The command
    grep -r . symlink_to_dir
should recurse into the directory pointed to by symlink_to_dir.
This patch fixes grep to implement this case.
This also fixes the newly added test in the testsuite.
