When I tried to drop the leading type character in the gopher selectors
I discovered the following problem.  The server receives the request

         /fooFsomedata

with `F' being a tab character.  Now the question for the server is if
`/foo' is of type 7 or not.  In the first case `somedata' is the query
string in the second it's a gopher+ attribute.

To answer this question and to continue the selector parsing the server
must first get the type of `/foo'.  This is possible but I prefer the
server to have a clear understanding of the selector before doing
anything else like analysing the request and the addressed item.  In
other words, I want to make the selector interpretation independent
from the available data.  Here the leading type character simply helps
the server to see how the whole request should be interpreted.
