Comment 1 for bug 671778

To clarify (as the 'someone on #sbcl'), the problem is that while the manual says "Exclude statements specify patterns of subdirectories the systems from which to ignore." it seems to be matching parent directories too, as in the example above while searching for SBCL contribs, which matches the default exclude of "CVS" subdirectories.

After looking further though, it may have been fixed in 2.139/2.010 while optimising directory search.
