problems with llParseString2List

with this code:

list math = llParseString2List(input, [" ","="], ["(", ")", "+", "-", "*", "/", "^", "sqrt", "asin", "acos", "atan", "sin", "cos", "tan", "n"]);
    llOwnerSay(llDumpList2String(math, ","));

Any of the spacers listed behind "sqrt" do not work properly. If they are entered adjacent to another character, as in "sin6", the sin does not get spaced when it is parsed. When I put a space between them, it works, because I have a " " seperator. Any of the spacers before sqrt works whether it is adjacent to something else or not. Or if I move "sin" or any other spacer in front of "sqrt", it works just fine. Why is this?

Sorry about the delay - saw this earlier and forgot to answer it.

See this thread.

An 8 spacer limitation eh? Such trials and tribulations.
