Remove duplicated module tags

[tssm]

Well, now that I have created the branch I realize this may not be the right change because *module* is an actual identifier, and apparently there's no way to escape the asterisks, but I'm creating the PR anyway in case someone else know a solution

The wrap-last-expr documentation is admittedly a little verbose, plus since the asterisks are treated as syntax the result is technically wrong.

I think for the help file this would be appropriate:

Used by aniseed.compile to ensure the current module is returned if necessary

Fixed in the roundabout way of just deleting the offending text 😬 I still don't know how you'd escape asterisk characters in vim help text though.
