- org-fontify-meta-lines-and-blocks-1
is looking for begin_
what comes after (src) is optional and can be anything
Next it looks for "language" (match-string 5 to 7
— it could be helpful to have comments indicating
the number matching of the groups next to them).
What gets fontified like a source block turns out to be:
,#+begin_{\w} <language> [<switches> <header arguments>]
So this is fontified:
#+begin_quote python
def sss(): pass
#+end_quote
and this too:
#+begin_fly awk
BEGIN { woosh }
#+end_fly
Which is nice, but not interpreted like so
by any export backend.

Makes more sense, yes.
I would have named them "directives"
rather than "keywords", but it's too late now.
