That will leave you without the fixed tr(1) first in the $PATH.

Although it looks like that's less relevant with Tony's change to use
the redundant square brackets.

I've applied a change which tries to fix $PATH and other environment
first, and then does a look for a better choice of shell. Dash first
(non-interactive, after all) then bash.

The more I use shell, the more I hate it.
