bug#24230: 25.1.50; vc-mode and svn+ssh:// URLs

[Alfred M. Szmidt]

When working with SVN repositories and doing C-x v l on a file I get
the following:

  Working file: /home/ams/Makefile
  svn: E170013: Unable to connect to a repository at URL 
'svn+ssh://carbonium/svn/com/ams/trunk/Makefile'
  svn: E210002: To better debug SSH connection problems, remove the -q option 
from 'ssh' in the [tunnels] section of your Subversion configuration file.
  svn: E210002: Network connection closed unexpectedly

Commiting and other operations fail as well, but only if one uses the
svn+ssh:// protocol.
