This reminds me of a problem lying around for a while. Tramp, like other
packages, sets the environment variable INSIDE_EMACS. So if you eval
--8<---------------cut here---------------start------------->8---
(let ((default-directory "/ssh::"))
(shell-command-to-string "echo $INSIDE_EMACS"))
--8<---------------cut here---------------end--------------->8---
you get "28.0.50,tramp:2.5.0-pre". But if you run in an eshell buffer
--8<---------------cut here---------------start------------->8---
~/src/emacs $ cd /ssh::
/ssh:detlef:/home/albinus $ *echo $INSIDE_EMACS
--8<---------------cut here---------------end--------------->8---
you get "28.0.50,eshell". Tramp's setting is overwritten.
Shouldn't the specifics be merged, so that we get
"28.0.50,eshell,tramp:2.5.0-pre"?
Same for the other packages setting INSIDE_EMACS, like compile, comint,
term and epg.
Best regards, Michael.
