--text follows this line--
I'm using Ubuntu 20.04 and the emacs version is:
GNU Emacs 29.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.20,
cairo version 1.16.0) of 2023-08-04
as seen when I look the emacs-menu help->About Emacs
In my .emacs file this line is present:
(setq-default indent-tabs-mode nil)
which, as far as I understand, shall make the default setting of this
variable (indent-tabs-mode) to be disabled, i.e. instead of inserting a
tab in the code-file, it shall insert a number of spaces, four to be
exact, according to this line in .emacs:
(setq-default tab-width 4)
This is what I want, and it has worked fine until recently. What I get now is that emacs insert a tab (\t) character instead. I suspect
that it broke during some upgrade of emacs, judging from the build date
of emacs it is updated recently, 2023-08-04
Further, if I disable the variable locally (M-x indent-tabs-mode) in a buffer it works, then I get four spaces, but
the variable has to be modified manually in every buffer I start.
I've also tried moving the (setq-default indent-tabs-mode nil) to the
last line in .emacs, if the variable was "implicitly overwritten" by
some other directive in the .emacs file. It had no effect.
So it seems to me the problem is that the default setting of this variable is ignored.
My complete .emacs is at the end.
