Is there any use in having a host named : or protocol nbd:? I don't
think so. The other examples could be achieved much easier by assigning
the file: protocol to raw, so we would have:
file:scsi:0:abc
file:http://myweb
This solution wasn't accepted last time because it wouldn't solve the
problems with other characters like commas (they need to be escaped as
double comma on the command line) and that won't be solved by this patch
either.
