[PATCH] daemon: parse_host_and_port SIGSEGV if port is specified

From: Imre Deak <redacted>

This typo will lead to git-daemon dying any time the connect
string includes a port after the host= attribute. This can lead
for example to one of the following error messages on the client
side when someone tries git clone git://...:<port>.

When the daemon is running on localhost:
  fatal: The remote end hung up unexpectedly

or when the daemon is connected through an ssh tunnel:
  fatal: protocol error: bad line length character: erro

In the latter case 'erro' comes from the daemon's reply:
  error: git-daemon died of signal 11
