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