* Status of [[ support:
* && and || work as they should
* = is glob match operator, not equality operator: STR = GLOB
- * (in GLOB, quoting is significant on char-by-char basis: a*cd"*")
* == same as =
- * add =~ regex match operator: STR =~ REGEX
+ * =~ is regex match operator: STR =~ REGEX
* TODO:
* singleword+noglob expansion:
* v='a b'; [[ $v = 'a b' ]]; echo 0:$?
* [[ /bin/n* ]]; echo 0:$?
* quoting needs to be considered (-f is an operator, "-f" and ""-f are not; etc)
