git-quiltimport complaining yet still working

There were two bugs: "stop_here" doesn't exist, but the bug that causes
this code to trigger in the *first* place is the wrong use of "$dotest".
It should be ".dotest"

This is essentially the same bug introduced by 87ab7992, one was
fixed with 0d38ab25 but this was somehow left behind.
