Subject: connect.c: ignore extra colon after hostname
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ignore an extra ':' at the end of the hostname in URL's like
"ssh://example.com:/path/to/repo"

The colon is meant to separate a port number from the hostname.
If the port is empty, the colon should be ignored, see RFC 3986.

It had been working for URLs with ssh:// scheme, but was unintentionally
broken in 86ceb3, "allow ssh://user@[2001:db8::1]/repo.git"
