TOC items and page headers contain "-" and ".md"

[rowansharman]

In both output modes, page headers and links are named identically to the .md files cloned from the wiki (spaces are replaced with dashes and .md is appended) unlike in the the sample PDF.

I assume the sample wiki had a custom _sidebar file defined, which contained a manually set table of content. Sadly, that repo no longer uses its wiki as the main page, so who knows :/

Workarounds:

1. Add _sidebar.md to wiki repo with following content:

   - [  ](#your_file.md)
   

OR

2. Add custom toc with same content and use option --toc

   gwtc  --toc testwiki_toc.md --title "My Title" --pdf-page-count --format pdf  ./TestWiki.wiki

Please fix this. It should try to mimmick GitHub's default sidebar style, which is what users expect.
