Sorry -- by itself the above change doesn't solve the problem. The
resulting pathname (/DOCUME~1/username/LOCALW~1/Temp) does not exist for
Cygwin's scp. In addition to the above change to tramp.el, I had to do
this in my .emacs startup file:
(setq tramp-temp-name-prefix "/temp/tramp.")
Then I had to make a symlink in my Cygwin root directory as follows:
$ ln -s c:/temp /temp
Doing this makes "/temp/tramp.xxx" in Emacs refer to the same file as
"/temp/tramp.xxx" on the scp command line in Cygwin.
Yes, this is a hack. A better solution would be for TRAMP to provide a
variable that maps the Emacs temporary directory to a Cygwin temporary
directory that is used in the second argument to the scp command. For
instance, the variable's value might be an assoc list of the form:
(("/tmp" . "/tmp")
("c:/temp" . "/cygdrive/c/temp"))
The first entry in the assoc list for which (file-exists-p (car entry))
is t is the entry that provides the mapping.
I can code this and submit a patch -- if the developers think it's the
right way to solve the problem.
