----------------------------
Implemented the feature request in issue 6: Support for milleseconds in
timespan parsing/formatting. Technically speaking this breaks backwards
compatibility but only by dropping a nasty (not documented) implementation
detail. Quoting from the old code::
All of the first letters of the time units are unique, so
although this check is not very strict I believe it to be
sufficient.
That no longer worked with [m]illiseconds versus [m]inutes as was
also evident from the feature request / bug report on GitHub.
