Ok, a couple of things:
wordexp is posix *not* bash. There's an important difference in that it
doesn't do as many crazy substitutions as bash does.
Also we can switch off the command substitution feature which makes things a
little simpler.

In addition, we need to standardise the escape character I think if we use glob as otherwise we're going to have ` for some things and \ for others, that's just a mess.
If you really want to keep your hand-rolled env var expansion,
then we definitely need the ${var} syntax,
and probably the \ as escape character to work with the glob call.

Cheers,
Adam.
