Exception thrown when parsing lists

[jwr]

When switching from 1.10.9 to 1.11.0 I noticed that markdown-clj is no longer able to parse some of my input files, throwing an exception.

I managed to narrow it down to this:

  (markdown/md-to-html-string "
 * A
* B")

(note the space before the first bullet point)

This results in:

              Numbers.java:  261  clojure.lang.Numbers/gt

@jecneps looks like we might have some regressions from the fix here #179
