Thanks a lot for your contribution! I've just merged your patches with these
additional changes by me:

* converted the tests to instead use the HTTP server (with a --gopher
   switch) to make them work better

* prevented a busy-loop

* fixed a memory leak

There's one (minor) problem left in the gopher code and I've added a big
comment blob in gopher.c about it:

The gopher_do() function sends the request in a loop-style which causes the
function to block until done. This is not fine for when the code is used by
the multi interface. Instead it should then send as much as possible in the
first shot and then continue sending the rest in a "doing" function.

A side-effect, a secondary flaw, is that the current code won't respect the
timeout during the request-sending loop.

I call this minor as I suspect that it won't loop there very often, nor is it
likely to block for very long.

PS, curl -V on my dev machine now show this rather impressive protocol and
feature output:
