Subject: [PATCH] clone: make sure we support the transport type
If we use an unsupported transport (e.g., http when curl
support is not compiled in), transport_get reports an error
to the user, but we still get a transport object. We need to
manually check and abort the clone process at that point, or
we end up with a segfault.
Noticed by Thomas Rast.
