bug#60796: 27.1; Opening file ending in .sh inside a directory ending in .deb causes hang/100% thread usage

[Casey Connor]

Oops, sorry, I just noticed the Cc on these emails that I should have 
been using. Repeating what I said in (accidental) privacy:

I installed Ubuntu Server 22.10 in a VM, booted, installed emacs-nox 
package from repo, did mkdir asdf.deb, cd asdf.deb, emacs -Q, and the 
problem happens there, in case that's useful. (v27.1)

I realized that it doesn't matter what you are editing (if anything), it 
just needs to be opened inside a directory ending in .deb.
