I believe this is incorrect, and the problem is deeper. The fix
should be done in the detection code, because 'undecided *is* useful
on no-Mule, to detect EOL conventions. The detection code should not
try to detect coding systems, but hardcode to raw-text.
Also problematic, AFAIK 'no-conversion is 'binary and thus forces Unix
eols. The right coding system would be raw-text, IIRC (although this
nomenclature may be screwed up for GNU compatibility).
(decode-coding-string "hi there\r\n everyone" 'no-conversion)
=> "hi there^M
everyone"
(decode-coding-string "hi there\r\n everyone" 'raw-text)
=> "hi there
everyone"
Good point. I was misled by the existence of no-conversion-{unix, dos, mac};
I thought that implied autodetection for the coding system without line
ending information, but that is not so.
Okay, I’ve made the below change and Tramp builds. It still seems to me that
undecided is not useful on no-Mule, given the existence of raw-text to do
line ending convention detection.

* coding.el:
Use raw-text, not no-conversion for iso-8859-1 on non-Mule;
preserves the line ending autodetection, but doesn't do coding
system autodetection. Thank you Stephen.
