Subject: bug#4902: 23.1; directory-abbrev-alist is not handled early enough
Date: Tue, 10 Nov 2009 12:54:06 -0500

Start emacs -q on a Windows system

In *scratch* buffer, evaluate

(setq directory-abbrev-alist '(("^/mount/" . "//uncpath/mount/")))

Even after setting this value, it is not honored on Windows.
Lower level functions appear to ignore directory-abbrev-alist,
so find-file and find-file-noselect etc. end up with "true" filenames that
contain drive letters:

(file-truename "/mount/somefile.x")
=> "c:/mount/somefile.x"

(expand-file-name "/mount/somefile.x")
=> "c:/mount/somefile.x"

(c:/mount does not exist, but //uncpath/mount/ does)
