use normalized documentation name when comparing to module name

When checking if a file should be marked as indexed, if the
documentation name (from the abstract) exists it is required to match
the module name. The module name is normalized to use double colons
rather than possibly apostrophes. Also normalize the documentation name
when doing this comparison.
