Summary: file:// and RFC1738

Initial Comment:
cURL supports file:// but doesn't conform to RFC 1738.

According to RFC 1738 file://remotehost/path/to/file
is a (informal) specification where a file can be
found in the filesystem on "remotehost".

Please see the following log of some curl commands run
on Windows (katmai IS localhost here):

valid URL):

R:\>curl -# -v -I file://marsupilami/e$/boot.ini
* Couldn't open file /e$/boot.ini
curl: (37) Couldn't open file /e$/boot.ini

\ ain't a valid char for URLs.
file:/// means file://localhost/, so
file://C:\something is invalid.

Please check RFC 1739 and 2151 too!

This is by design and you will also note that the RFCs do
not specify _how_ that getting of a file from another system
is supposed to be done.

If you feel like extending curl to do this, I'm sure lots of
users will enjoy it as I certainly will. I personally have
no plans to implement anything like this for the forseeable
future.
