bug#73881: 31.0.50; Unexpected warnings about recursive occurrences of obsolete functions

[Eshel Yaron via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

1. emacs -Q
2. (require 'allout) or otherwise load allout.el
3. Byte-compile allout.el with M-x byte-compile-file
4. See warnings:

--8<---------------cut here---------------start------------->8---
In allout-old-expose-topic:
allout.el:5092:29: Warning: ‘allout-old-expose-topic’ is an obsolete function
    (as of 28.1); use ‘allout-expose-topic’ instead.
allout.el:5097:44: Warning: ‘allout-old-expose-topic’ is an obsolete function
    (as of 28.1); use ‘allout-expose-topic’ instead.
allout.el:5106:8: Warning: ‘allout-old-expose-topic’ is an obsolete function
    (as of 28.1); use ‘allout-expose-topic’ instead.
--8<---------------cut here---------------end--------------->8---

These warnings are unhelpful since these are recursive calls within the
definition of the obsolete function itself.  They need not be replaced
with another function as the warnings suggest.  Ideally, recursive calls
to obsolete functions should not produce such warnings.


Best,

Eshel
