Backpatch addition of pump_until() more completely. 

In a2ab9c06ea1 I just backpatched the introduction of pump_until(), without
changing the existing local definitions (as 6da65a3f9a9). The necessary
changes seemed more verbose than desirable. However, that leads to warnings,
as I failed to realize...

Backpatch to all versions containing pump_until() calls before
f74496dd (there's none in 10).
