Description of problem:
On my 64-bit system, cvsps makes a bogus attempt to connect to 255.255.255.255 because it fails to determine whether the given hostname could be parsed as a dotted-decimal IP address.

Version-Release number of selected component (if applicable):
cvsps-2.2-0.4.b1.fc11.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. rm -f ~/.cvsps/":pserver:anonymous.org:#cvs#pkgs#rpms#cvsps"
2. strace -e trace=connect cvsps --cvs-direct --root :pserver:anonymous.org:/cvs/pkgs rpms/cvsps
  
Actual results:
connect(3, {sa_family=AF_INET, sin_port=htons(2401), sin_addr=inet_addr("255.255.255.255")}, 16) = -1 ENETUNREACH (Network is unreachable)
connect error: Network is unreachable
