I've looked into finding regular expressions for similar features
(parsing command lines and taking quotes into account), and the
expressions basically work by full enumeration of the various quote
options -- much like what the Java code we have does.  You could rewrite
it with a regex, but I don't see why.  I think the Java code we have
works in 100% of cases (I did a lot of testing on it) and works on older
JDKs.
