IMHO this is ambiguous.  It's not clear whether "do not start with a dot" is
referring to the filename or a path component starting with a ".", and if it's
referring to a path component it's not clear which path component.

If I understand the code change correctly I believe that directories descended
from the analysis root will be excluded from analysis if the directory name
begins with ".", but that files whose names begin with "." will in general still
be analyzed.  Also, if an analysis root contains a path component that begins
with ".", that will not prevent analysis.
