Include macro doesn't work with relative wiki links

[Jim Sermersheim]

From a wiki page called "Parent":

This works: [[Include(Parent/Child)]]

This doesn't work: [[Include(Child)]]

[Steffen Hoffmann]

This has been ​requested on the mailing list again recently.

Btw, the example in the description is bogus, because scoped wiki link resolution in Trac core searches siblings of the current page, and then looks upwards on the path, never downwards, as suggested.

proposed patch for adding relative wiki page resolution for wiki page includes

[Steffen Hoffmann]

Note: I've shortened the code by using existing _split_path function to extract optional wiki page version too, what is unrelated to the solution.

some PEP8 and nit-picking on doc-string and comment style

[Steffen Hoffmann]

The second patch just proposes some code clean-up, especially shortening line length in multiple places. Apply at as you like.

Thanks for the patches. Feel free to push your changes and I'll do a retrospective review when I have some time.
