No, I mean what was said in the thread I referred to, namely:

which works without the need for enabling eval of local variables. But it's
a little ugly, and doesn't work right, since it still prints "indentation
set up for shell type bash". I'd prefer just a single variable that
controls what shell flavour a file is.
That solution really does not seem solid at all. Not only is the
indentation wrong, but moreover sh-shell is now csh, whereas
sh-shell-file still has its usual value, in my case
"/usr/local/bin/bash". This means half of sh-script.el thinks you are
programming for csh and the other half thinks you are programming for
bash. This is bad. I doubt that the problems caused by that are
limited to the indentation problems (which are bad enough anyway.)
I personally believe that the only solid way to switch shells is to
call sh-set-shell. Otherwise, you have to emulate everything
sh-set-shell does, including (run-hooks 'sh-set-shell-hook). This
seems hopeless.
Is having enable-local-eval set to maybe (the default-value) that bad?
(It is not going to execute any evals without asking you.) If it is,
one could have sh-mode look for a definition of sh-shell-file in the
local variable line, if there is no magic number. Then you could just
set sh-shell-file and sh-mode would itself call sh-set-shell with the
desired argument.
Can anybody think of a simple, but thoroughly solid, solution, not
involving code changes, that works when enable-local-eval is nil?
Sincerely,
Luc.
