is not the expression to test whether both "$foo" and "$bar" are
non-empty, as it would fail for some specific values of $foo or
$bar (try it when $foo contains "=" for instance).
Huh? Why would having an '=' in foo have any effect?
I think Stephane meant the exact string "=", not any string containing
"=".
Ah, yes, *that* would cause problems.
/me reads "contains" in the string sense, not the value sense :-)
