[PATCH v1 1/1] connect: [host:port] is lagacy for ssh

[tboegi@web.de]

From: Torsten Bögershausen <tboegi@web.de>

Early versions of the parser in connect.c handled
git clone [host:123]:/path the same as
git clone ssh://host:123/path

Keep that feature as legacy, but disable it for all other protocols.
Everything inside [] should go into the host part.

Signed-off-by: Torsten Bögershausen <tboegi@web.de>

This is my attempt to keep the legacy for ssh only,
and fixes my comments
