Markdown reader: Fix parsing of consecutive lists.

Pandoc previously behaved like Markdown.pl for consecutive
lists of different styles. Thus, the following would be parsed
as a single ordered list, rather than an ordered list followed
by an unordered list:

    1. one
    2. two

    - one
    - two

This patch makes pandoc behave more sensibly, parsing this as
two lists.  Any change in list type (ordered/unordered) or in
list number style will trigger a new list. Thus, the following
will also be parsed as two lists:

    1. one
    2. two

    a. one
    b. two

Since we regard this as a bug in Markdown.pl, and not something
anyone would ever rely on, we do not preserve the old behavior
even when `--strict` is selected.
