/* We do not handle [[ expr ]] bashism bash-compatibly,
* we make it a synonym of [ expr ].
* Basically, word splitting and pathname expansion should NOT be performed
* Examples:
* no word splitting: a="a b"; [[ $a = "a b" ]]; echo $? should print "0"
* no pathname expansion: [[ /bin/m* = "/bin/m*" ]]; echo $? should print "0"
* Additional operators:
* || and && should work as -o and -a
* =~ regexp match
* Apart from the above, [[ expr ]] should work as [ expr ]
