Marku doesn't recognize lists with two or three spaces before the list mark

[weakish]

Quoted from markdown syntax:

List markers typically start at the left margin, but may be indented by up to three spaces.

But Marku only recognizes lists indented by zero or one space.

Example:

This is a list:

* a list

This is a list, too:

 * another list

But this is also a list:

  * yet another list

And this:

   * still a list

Confirmed for the current version of maruku.
Reason lies in `lib/maruku/input/type-detection.rb' (line 60ff.):

# Something is wrong with how we parse lists! :-(
#return :ulist    if l =~ /^[ ]{0,3}([\*\-\+])\s+.*\w+/
#return :olist    if l =~ /^[ ]{0,3}\d+\..*\w+/
return :ulist    if l =~ /^[ ]{0,1}([\*\-\+])\s+.*/
return :olist    if l =~ /^[ ]{0,1}\d+\.\s+.*/

The regexes accept only one or two leading spaces.

PS. Simply changing {0,1} to {0,3} or using the commented out lines breaks some test cases.

PPS. kramdown, pandoc, and the "original" Markdown.pl all work as expected.

Is it possible with maruki 0.6.0 to create a nested list? I left a comment on #55 with the syntax I'm trying. Can't seem to find the magic indentation to create proper nested lists.
