- The leading string up to delim is returned in piece (not including
- delim), while the original string is cut from after the delimiter.

+/** Splits the string given in the first argument at the first occurence
+ of the third argument, delim.
+ What precedes delim is returned in the second argument, piece; this
+ will be the whole of the string if no delimiter is found.
+ The return value is what follows delim, if anything. So the return
+ value is the null string if no delimiter is found.
+ 'a' and 'piece' must be different variables.
+ Examples:
\code
- s1= ""; s2= "a;bc".split(s1, ';') -> s1 == "a"; s2 == "bc";
+ s1= "a;bc"; s2= ""
+ ret = split(s1, s2, ';') -> ret = "bc", s2 == "a"
