| GNU Coding Standards frown upon using "path" for anything except
| PATH-style lists of directories.  Use "file name" or "leading
| directories" instead.

| What will this do to text such as the one below?
| 
|  C:\emacs\bin\prog1.exe on Windows or /usr/bin/prog1 on Unix.

User can enable/disable if spaces are taken into account. If enabled,
the result is:

  "C:\emacs\bin\prog1.exe on Windows or /usr/bin/prog1"

If disabled, depending on cursor position:

  "C:\emacs\bin\prog1.exe"
  "/usr/bin/prog1"

If you have strategiy to make it better, please suggest.

| What about Posix-standard /foo/bar/baz, which is the usual case on
| Cygwin?

Only "<drive letter>:" is converted into "/cygdrive/<drive letter>" under
Cygwin.
