Xalan-c: indexOf(), lastIndexOf()

The Java support routines indexOf(), lastIndexOf() in DOMStringHelper.cpp
returns the length of the string when the character is not found. The Java
spec says it should return -1. Is this by designed or a bug? Returning the
length makes me need to do a strlen() to tell if the character wasn't found.

Another thought, returning length instead of -1 means your compiled code
will be more inefficient. -1 is a constant and length is a variable. It is
much easier for the compiler to compare and optimize with a constant.
