Subject: [PATCH] Option to not require .md extensions in markdown links

Gitlab uses markdown in an interesting way. If you want to create a link
to the page "linked-to-page" you might do this:

[Linked To Page Title](linked-to-page)

And not,

[Linked To Page Title](linked-to-page.md)

This change is about having the "ge" command work on wiki links
constructed in this way, and provides consistency between how gitlab
works and vim-markdown works.

The default behaviour is not affected.

+### Do not require .md extensions for Markdown links
+
+If you want to have a link like this `[link text](link-url)` and follow it for editing in vim using the "ge" command, but have it open the file "link-url.md" instead of the file "link-url", then use this option:
+
+```vim
+let g:vim_markdown_no_extensions_in_markdown = 1
+```
+This is super useful for GitLab and GitHub wiki repositories.
+
+Normal behaviour would be that vim-markup required you to do this `[link text](link-url.md)`, but this is not how the Gitlab and GitHub wiki repositories work. So this option adds some consistency between the two.
