Oh, found it: it's (defcustom vc-ignore-dir-regexp ;; Stop SMB, automounter, AFS, and DFS host lookups. locate-dominating-stop-dir-regexp "Regexp matching directory names that are not under VC's control. The default regexp prevents fruitless and time-consuming attempts to determine the VC status in directories in which filenames are interpreted as hostnames." :type 'regexp :group 'vc) used by VC. I suggest you report it as a bug: vc-ignore-dir-regexp should only "extend" locate-dominating-stop-dir-regexp but not override it (at least by default). Stefan
