Ok, I've tested in all the combinations I can, with the results in
the table below. "tramp-dev" is the latest Git revision, whereas
"tramp-2.5.0.4" is the version on GNU ELPA. I tested against the Win32
versions of OpenSSH (both v7.7 and v8.1) as well as the MSYS2 version
(I have v8.3). The "spaces" test is attempting to open `~/foo
bar.txt', and "quotes" is attempting to open `~/a "quoted" file.txt'.
I've also included the scp command, and the error message, if any.
(I saved logs with `tramp-verbose' set to 6, but they're pretty large
even compressed, and I'm not sure they'd be that useful anyway. If you
want me to send them over, just let me know.)
>From my tests, the best version combination is Tramp 2.5.0.4 with the
MSYS2 port of OpenSSH: both files open correctly. However, the
development version of Tramp *is* an improvement for anyone with
Win32-OpenSSH v8.1.
Would it be possible to enable your fix only for the Win32 version? It
looks like you can tell them apart by checking `ssh -V'. The Win32
version looks like:
OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5
and the MSYS2 version looks like:
OpenSSH_8.3p1, OpenSSL 1.1.1g 21 Apr 2020
I mentioned it in the other thread, but I'm starting to think that the
MSYS2 port of OpenSSH is the best way to use SSH on MS Windows. It
seems that it even supports the ControlMaster option, so Tramp could
use it on MS Windows, and only disable that feature when it detects
"OpenSSH_for_Windows".
