-% \iupac (basically the same as bpchem's \IUPAC)
-% - allows multiple breaking points as compound names can get really long and
-% especially in multicolumn documents can span more than two lines
-% - add a (very) little space before the hyphen and a little negative space
-% after it
-% - add a little space at breaking points if not broken
-% - enables all naming commands regardless if they're definied otherwise or not
