Subject: bug#75308: 30.0.93; man.el assume shell is bash
Date: Fri, 03 Jan 2025 09:39:09 +1000

Steps to reproduce:
* env SHELL=/bin/tcsh emacs -Q
* invoke M-x man
* request a man page (e.g. emacs)

This will produce output like the following instead of the man page:

    Unmatched '''.
    BEGIN: Command not found.
    anonblank=0: Command not found.
    }: Command not found.
    Illegal variable name.
    {: Command not found.
    }: Command not found.
    Illegal variable name.
    Badly placed ()'s.
    Unmatched '''.

    process exited abnormally with code 1

Replacing /bin/tcsh with /bin/bash in the above command produces the
expected man page.

It looks like the behavior was broken by the following commit:

    commit 861ac933dd8aed1028edc4b9142400e3702874d5

Many thanks,
