+There is a `MKD_NOALPHALIST` option to discount (assuming that's the Markdown implementation you're using), but it isn't clear which way should be preferred in general.
+
+With that option off, people complain that they can't have alphabetical sub-lists (Google for \"markdown alpha list\" to see this feature request in various places).
+
+With that option on, you get unexpected results for things like your example. It's also liable to break initials (`S. J. McVittie is an ikiwiki contributor`) or the French abbreviation for Monsieur (`M. Poirot is a famous French-speaking detective`).
+
+The original Markdown didn't have lettered lists; neither does CommonMark, although it's a feature request in CommonMark.
