question about list item levels in AST

question about list item levels in AST

How does the list item levels get represented in the AST?

Say I issue the command:
$ pandoc -f markdown -t native
* Item 1
* Item 2
  * Item 2a
  * Item 2b

this is what I got:
[BulletList
 [[Plain [Str "Item",Space,Str "1"]]
 ,[Plain [Str "Item",Space,Str "2"]]
 ,[Plain [Str "Item",Space,Str "2a"]]
 ,[Plain [Str "Item",Space,Str "2b"]]]]

It seems to me that in the output AST all four list items are in the same 
level, but the markdown text clearly says that item 2a and 2b are a 
sublist. Why?

Thanks,
Jeff

OK I got it. It's all about sufficient indentation.

* Item 1
   * Item 1a

gives

[BulletList
 [[Plain [Str "Item",Space,Str "1"]]
 ,[Plain [Str "Item",Space,Str "1a"]]]]

and 

* Item 1
       * Item 1a

gives

[BulletList
 [[Plain [Str "Item",Space,Str "1"]
  ,BulletList
   [[Plain [Str "Item",Space,Str "1a"]]]]]]

As aside, the indentation is spaces or tabs does not seem to matter though.

By the way, is there a function that, given an input string s whose prefix 
is a mixture of space and tabs, outputs the length of total indentaion?

No.  You only have two spaces indent, it looks like.
See http://pandoc.org/MANUAL.html#the-four-space-rule
Also issue #3511
