I wrote one once for C (actually B!) quotes,
and it was mildly hairy.
Hmmn: or is it???
I suspect we want to evaluate all the `` and $var
constructs, so that the program called gets the right
information, and just protect against tokens like
"foo bar" turning into multiples...
Does that make sense? That would make:
open hook = scriptName %U "weegle woggle"
should turn into
popen("scriptName \"%U\" \"weegle woggle\"" ,"r");
