Description of problem:
the ifup-ppp script starts ppp-watch for demand-dial links, but it is not 
necessary (and in fact it gets in the way, because ifdown-ppp kills the 
pppd process for a demand-link before killing ppp-watch, and ppp-watch 
sometimes will restart pppd)

How reproducible:
Always

Steps to Reproduce:
1.Configure ifcfg-ppp0 with DEMAND=yes
2.Execute ifup ppp0
3.Check for ppp-watch running
	

Actual Results:  it will be there :-)

Expected Results:  it shouldn't be there :-)

Additional info:

here is a patch to fix the problem (against initscripts-6.10-1):
