That's a possibility, but note that "pwd -W" requires that you cd into
the directory first, which might be a problem in some rare cases.

Also msys_lisppath_to_w32 works on PATH-style directory lists, not on
single directories, and some of those directories might not exist, or
include %emacs_dir%, which will cause pwd to fail.

If these difficulties can be overcome, I have nothing against using
"pwd -W".
