With following dir structure:
         -wine+
              +-drive_c+
                    +test+
                         +test.txt
                    +test2.txt
              +-dosdevices+
                     +c:->../drive_c

With  only 'walk' method enabled I launch catfish in 'dosdevices' directory and search for 'test'.
On 1.4.10 I find 'test.txt' and 'test2.txt'.
On 1.4.11 I find 'test.txt' only.
Correct would be to find 'test.txt', 'test2.txt' and 'test'

My previous patch that fixed the link looping (cac84de5) introduced this bug, I attached a patch to fix it
After applying it the search results seem to be correct.
