bug#993: 23.0.60; vc-find-root heuristic unreliable on Windows with Cygwin

[Glenn Morris]

Presumably this is now fixed, owing to these changes:


2008-10-25  Stefan Monnier  <monnier@iro.umontreal.ca>

    * files.el (locate-dominating-stop-dir-regexp): New var.
    (locate-dominating-file): Change arg from a regexp to a file name.
    Rewrite using the vc-find-root code to avoid directory-files which is
    too slow.  Obey locate-dominating-stop-dir-regexp.
    Don't pay attention to changes in owner.

[...]

    * vc-hooks.el (vc-find-root): Use locate-dominating-file.
    (vc-ignore-dir-regexp): Use locate-dominating-stop-dir-regexp.


Though now I have a bunch of bogus automounter queries cluttering up
my logs again, which I have some vague memory was the reason for the
change of ownership test in the first place...

Time to customize locate-dominating-stop-dir-regexp I suppose...
