Subject: 30.0.50; Emacs reloads init file when calling `documentation'
Date: Tue, 02 Jan 2024 02:53:50 +0100

Hello,

I see this problem for a couple of weeks now, never saw it before:

When I made edits to my config file, any running session of Emacs that
has loaded this init file (including the same session) will have an
issue: any action that causes `documentation' being called with one of
the things defined in my init file as argument will reload the complete
init file.

This is a problem: it takes a lot of time and this can happen
repeatedly, often I have to restart Emacs to be able to continue my work
normally.  There are a lot of things that trigger the call of
`documentation' - not only requesting documentation explicitly, but also
things like `eldoc-mode' or cl-printing expressions.

I have not been able to find out why the behavior has changed.  The
reloading happens from C AFAIU.  Please help!

TIA,

Michael.
