[PATCH 1 of 2] testsuite: add (currently failing) test for -r on symlink to dir

[Thomas De Schampheleire]

'grep -r' on a symbolic link to a directory should follow the link.
This patch adds a test to the testsuite to verify this, which currently
fails due to grep not handling this case.
A subsequent patch will actually fix the behavior of grep.

Note: I split the test from the fix to simplify verification of these
patches. If you prefer, I can fold both patches into one.
