Hello all,
For quite some time, this small issue had been bugging me. I enable
org-eldoc by default and each time I put the point in an org src
block, I would see this error:
eldoc error: (error Lisp nesting exceeds ‘max-lisp-eval-depth’)
Here's a snippet of the full backtrace where we see the
`org-eldoc-documentation-function` being entered repeatedly until we
hit the max-lisp-eval-depth:
=====

Recipe to create this error:
1. Create a file test.org with these contents:
#+begin_src org
,#+html: foo
#+end_src
2. emacs -Q
3. Load/evaluate org-eldoc.el from
https://git.sr.ht/~bzg/org-contrib/tree/master/item/lisp/org-eldoc.el
4. Open the test.org file and place the point *inside* the org src block
5. eldoc error: (error Lisp nesting exceeds ‘max-lisp-eval-depth’)
-----
Upon inspecting the `org-eldoc-documentation-function` function, I
don't see a reason why the control should enter the default of `t'
case if the src lang is "org". Just returning with nil works for me if
the lang is "org". I will send a patch for this in a follow-up email.
