Hello,
an example: `manual-entry' is an alias for `man'. When now the alias is
advised, for example like
(advice-add 'manual-entry :filter-return #'identity)
and you do C-h f manual-entry RET, the first line of the Help buffer
will say:
| manual-entry is an alias for ‘nil’, which is not defined.
which is obviously nonsense.
Seems that this regression in `help-fns--analyze-function' had been
introduced by
d30fde6b0cc "Avoid infloops in help-fns--analyze-function with aliases"
(Lars Ingebrigtsen <larsi@gnus.org> 2022-01-13)
I CC Mattias and Stefan you might be able to help.
TIA,
Michael.

Right. This is a regression in Emacs 29.
The fix is going to master for now. Whether and when to backport it is Eli's decision to make.
Thank you for localising and reporting it!
