"pscp" is also chosen, when putty is installed on a GNU/Linux
system. This might not be the preferred choice.

I would prefer to reorder the check, meaning that scp takes precedence
over pscp. However, this raises problems with cygwins's scp, which does
not cooperate with Tramp pretty well.

Is there a cheap test for the presence of scp, NOT being the cygwin one?
Or shall we take pscp only in case of

      (memq system-type '(cygwin windows-nt))

?
