Subject: Draft fix and test case for formulas like Mg3(PO4)2.

Draft fix and test case for formulas like Mg3(PO4)2.

Also improve some comments to hopefully make it easier for future
developers to understand what the code is supposed to be doing.

There's no update to the "Formatting rules" in the readme because this
brings the code into better alignment with what that section already
said.
