Hmm, yeah. We'll need to do something with the Tramp case. I think the
minimal fix would be to update `tramp-sh-handle-make-process' so that it
doesn't signal an error when :connection-type is a cons cell. That's
pretty easy.
However, it seems that Tramp doesn't fully support :connection-type yet
(testing on both Emacs 28.1 and 29). I used the following Python script,
and tried a few varieties of `make-process' calls over Tramp. I'd expect
that when I set :connection-type to `pipe', it would print False for all
the streams, but it seems that the script always sees stdin and stdout
as TTYs no matter what options I use.
------------------------------
#!/usr/bin/env python3
import sys
print('stdin: {}\nstdout: {}\nstderr: {}\n'.format(
sys.stdin.isatty(),
sys.stdout.isatty(),
sys.stderr.isatty()
))
------------------------------
On the other hand, if I set :stderr to be a buffer, then the script
*does* see stderr as a pipe, but that makes sense looking at the code:
when using :stderr, Tramp redirects the process's stderr to a file (and
then cats it back out).
Maybe there's a relatively easy way to get Tramp to respect
:connection-type, but I tried a couple of things and they didn't work
quite right. Still, that could be a followup for later. So long as it
doesn't error out immediately when it's a cons cell, I think it would be ok.
