This isn't reliable either: bash 3.1.17 and ksh do this:
$ ( d=:a:b:; IFS=:; for i in $d ; do echo .$i. ; done )
..
.a.
.b.

but pdksh does this:
$ ( d=:a:b:; IFS=:; for i in $d ; do echo .$i. ; done )
..
.a.
.b.
..

So effectively the above starts adding '.' in $PATH for pdksh.
Similar for zsh.  And I've only tested on GNU/Linux so far.

Yucc.  This is uglier than I thought, adding in that I think SUSv3
wording is saying that pdksh is right and bash is wrong.  :-/
