+Ok, I wrote quite a few lines why hash instead of command -v,
+just to finally notice this:
+
+$ dash -c 'hash zapdsb=C2=A0|| echo foo'
+dash: 1: hash: zapdsb=C2=A0: not found
+foo
+
+which is ok... but:
+
+$ ksh -c 'hash zapdsb=C2=A0|| echo foo'
+$ mksh -c 'hash zapdsb=C2=A0|| echo foo'
+
+Wat! hash in these shells do not exit nonzero -- so good with my which(1)
+rant >;/
+
+So I change my preference totally -- `command -v` instead of `hash` -- we
+have to fix the current uses of `hash` too...
