" How it works: Jinja files may have a compound file name like

" 'foo.html.jinja' or 'foo.tex.jinja'.  We trim off the '.jinja' (or '.jinja2'

" or '.j2') part of the file name and try detecting the file type type.  If

" one is found we append '.jinja' to the file type.  Otherwise we use just

" `jinja` for the file type.

"

" There are separate implementations for Vim and Neovim because I could not

" make one solution work for both.
