// Strange things happen if you use this function twice on the same CHARRANGE:
// if Math-startDelimiter == Math-endDelimiter, there is the following problem:
// it might be that someone forgot an endDelimiter, this results in a lonesome startdelimiter.
// if you try to MATH_REPLACE_FORMULAE the second time, startDelimiters and endDelimiters are mixed up.
// The same problem occours if we have empty formulae, because two succeding delimiters are
// replaced with a single delimiter.
