---------- version 1.1.9 ----------
[w2l] The StarMath now avoids more redundant braces
[w2l] Properly detect and ignore empty formulas (avoiding any occurrences of $ $ in the document)
[w2l] The StarMath converter now avoids redundant braces
[w2l] The StarMath converter is now a little more tolerant on errors like missing operands for a binary operator
(import from MS Word may create such errors)
