Fixed width areas elements

[gzagatti]

I have noticed that the grammar implemented here does not support "Fixed width areas" elements which basically are paragraphs that start with the colon character followed by space.

These elements are usually used to denote code evaluation output. For instance:

#+begin_src python
1 + 1
#+end_src

#+results: 
: 2

Is this a deliberate choice? It would be nice to have such support.

Great question, I think the best implementation here would use a query to find those elements, for example:
(paragraph (directive name: (_) @name (#eq? @name "results")) . (expr) @start (#eq? @start ":")) @results_region, is a query that should find elements that look like that (I can't test at this moment), but doesn't guarantee each subsequent newline starts with a :. Depending on the tree-sitter implementation used, a #match? predicate should be used to ignore case on "results".

I'm not eager to, but not against adding fixed-width areas. I'll look into it for a bit, thanks for the suggestion.
