Description

When I scan a directory sccs(or rcs) with sub-directory(such as rcs/a), the scan scan fails with keyerror.
Note 1: I've scanned a git directory with .git & it works without error.
Note 2: when I comment out '/rcs' and '/sccs' in src/commoncode/ignore.py, there's no error.

[khoale:~/workspace/test]> mkdir sccs
[khoale:~/workspace/test]> mkdir sccs/a
