RFR [9] : get_source.sh should be more friendly to MQ

[Jonathan Gibbons]

Popping all patches beforehand is reasonable, but afterwards, it would 
be better to reset to the patches that were previously applied than to 
try and push all of them.

What is the behavior if you cannot qpush patches after the pull, because 
of merge issues?
