Harness script changes: filename section number dependence and help link whitespace

I removed the indexer script's dependence on having the primary spec section number
in the file name. (The information is now gleaned from the help links.)

I also fixed a help link regex problem that caused several of Boris Zbarksy's tests
to be left out of the generated index.

Diff attached.
