Changing PS1 had no discernable effect, but then I tried it _after_ starting 
up the shell, so perhaps it snapshots the value once on boot?

The code seems to try to set a default at line 1520, and again (a _different_ 
one) at lines 1661 and 1664.

Is it just me, or does ash contain a lot duplicate code working at cross 
purposes and winding up with a result of "neither"?  (The fact that file 
starts with the GPL and _ends_ with the BSD license is just one more fun 
example of this.)
