Merge 21404 - Fix a FORWARD_NULL defect in ExtractModuleName reported by Coverity.
If 'sep' is still NULL after the for loop, ix must be 1, so
ix == 0 cannot be true.

Update the comment for ExtractModuleName in the header to match
the implementation.  I don't see any code that checks whether the
path is a full path.
