Hi,
from org 9.5.3-g69c588
PATCH 1/2:
Having several programming books converted to org,
I read a lot of begin/end_src expressions. The
following patch helps lessen the visibility of
those terms: they are syntax tokens and can be
replaced my colors.
So this gives different faces to the language
specifiers and begin_ words, to attenuate
begin_/end_src and emphasize the language selected.
The picture in the attachment shows how source
blocks get rendered then. Don't mind too much
the "begin_quote" on it, as it's intended to
be "begin_src" under normal circumstances.
PATCH 2/2:
org/lisp/org.el::4966
#+begin_src elisp
;; Set face extension as requested. FIXME
;; (org--set-faces-extend '(org-block-begin-line org-block-end-line)
;; org-fontify-whole-block-delimiter-line)
#+end_src
I turned off those two lines otherwise the extend
property of org-block-begin-line and org-block-end-line
would keep coming back even after customizing them
("but I just did untick that box!")
When org-fontify-whole-block-delimiter-line is set to nil,
the block background start after /#+begin_src elisp/.
When it isn't set, an underline will run all over the line.
have a nice day,
Phil

The idea is reasonable and also in line with our inline src block
fontification. However, we are currently switching the fontification
backend. Hence, I'd prefer to postpone this patch to later. It will need
to be adapted to the new fontification code.
See https://orgmode.org/list/87ee7c9quk.fsf@localhost
Best,
Ihor
