tramp 2.1.11 uses reg.exe, not in Windows 2000.

[Wagemans, Peter]

During an upgrade attempt to tramp 2.1.11 from the default 2.0.55
included with GNU Emacs 22.1.1 (i386-mingw-nt5.0.2195) on Windows 2000
SP4 I encountered problems caused by tramp trying to call a program
that it couldn't find:

tramp.el:2039:                      (zerop (call-process "reg" nil nil nil "query" (nth 1 (car v)))))
tramp.el:5097:      (when (zerop (call-process "reg" nil t nil "query" registry))

The intention here is probably "reg.exe", but that is not a standard
part of Windows 2000.  A tool reg.exe does exist in the "Windows 2000
Service Pack 4 Support Tools" package, sp4supporttools.exe, which can
be downloaded from
http://www.microsoft.com/downloads/details.aspx?FamilyID=f08d28f3-b835-4847-b810-bb6539362473

I would like to suggest that tramp either checks for the existence of
this tool before calling it or that the dependency is pointed out and
download information is provided in the documentation.

Peter Wagemans
