Bug#775883: cvsps chokes on servers that print more than one "M" response to "version" command

[Richard Hansen <ubuntu-a7x@scientician.org>]

Package: cvsps
Version: 2.1-6
Tags: patch

If the CVS server prints more than one "M" response line to the
"version" command, cvsps prints "cvs_direct: protocol error reading
version" and fails to read the repository.

For example, cvsps does not like the following exchange:

Client: version
Server: M Concurrent Versions System (CVS) 1.12.13 (client/server)
Server: M with CVSACL Patch 1.2.5 (cvsacl.sourceforge.net)
Server: ok

I know that cvsps has been deprecated upstream in favor of
cvs-fast-export, but it is still used by 'git cvsimport'.
