Small bug with pppctl

[vze2ztys at verizon.net]

Hello,

I noticed that using pppctl interactively doesn't work quite right, at least for certain commands that produce a lot of output.  I cut and pasted a few invocations
to show what works and what doesn't quite work:

$ pppctl /var/ppp/ppp      
PPP ON bogushost2> show route
Destination         Gateway             Flags  Netif
Connection closed
$ pppctl /var/ppp/ppp 
PPP ON bogushost2> show ?
(o) = Optional context, (c) = Context required
Connection closed
$ pppctl /var/ppp/ppp 
PPP ON bogushost2> help
(o) = Optional context, (c) = Context required
Connection closed
$ pppctl /var/ppp/ppp 
PPP ON bogushost2> close
PPp ON bogushost2> 
ppp ON bogushost2> 
Ppp ON bogushost2> 
PPp ON bogushost2> 
PPP ON bogushost2> quit
