ash: eval: Return status in eval functions
Backported from dash:
eval: Return status in eval functions
The exit status is currently clobbered too early for case statements
and loops. This patch fixes it by making the eval functions return
the current exit status and setting them in one place -- evaltree.
Harald van Dijk pointed out a number of bugs in the original patch.
