The https link-type opens the local copies of the Spacemacs documentation files with
the spacemacs/view-org-file function. It supports GitHub style heading links
For example, the link:
https://github.com/syl20bnr/spacemacs/blob/develop/layers/org/README.org#links
Will be handled similary to as if it was:
file:~/.emacs.d/layers/org/README.org::*links
Also the `space-doc' mode will be applied.
Refactored GH style anchor search.
`space-doc-mode` - Buffer local minor mode for Spacemacs documentation files. The mode hides org meta tags.
Enabled when viewing documentation via `SPC` `h` `SPC`
