2015-03-27 09:56 AEST by Arthur Barrett - The server error messages can appear mangled on a Windows CMD prompt because of rouge \r CR 
(carriage return, no line feed) characters embedded in the message.

eg: the message should be:
cvs rls: warning: unrecognized response `'ssh' is not recognized as an internal or external command,' 
from cvs server
cvs rls: warning: unrecognized response `operable program or batch file.' from cvs server
cvs [rls aborted]: end of file from server (consult above messages if any)


but appears as:
cvs rls: warning: unrecognized response `'ssh' is not recognized as an internal
' from cvs servernd,
' from cvs server unrecognized response `operable program or batch file.
cvs [rls aborted]: end of file from server (consult above messages if any)


The code is in client.cpp in the function get_server_responses():

	    error (0, 0,
		   "warning: unrecognized response `%s' from cvs server",
		   cmd);


The problem is 'cmd' has CR in it, which then mangles the message.  The client should 'replace' any non-
printing characters (particularly CR) to fix this.
