Agreed. The whole chain started with my observation of very slow
access to files under UNC when compared to XEmacs. In an earlier
posting, I was told it was due to XEmacs using something like
find-file-literally and Emacs using find-file (which has lot of
hooks). It was debuged and found by Mr.KOBAYASHI Yasuhiro and the
original patch. I found the regex was not working for me from the
original patch and Stefan came up with the current regexp which
_tremendously_ speeds up accessing files over UNC. They have now
generalized for UNC,net and afs (not sure of this ,though)

I agree with you here. This variable could be in a more generic
location with a different name too. Ex: remote-folder-regex or
something like that and this should be defcustom. The default can be
the one in the patch.
