This happens because each of the list items is in a separate list,
making the numbering restart from one. Since the lines between the
list items are not indented by three tabs, there is not way to treat
this as a single list while conforming to CommonMark, if I understand
the list handling specs correctly.
The input leading to this can be seen at
https://dropbox.suckmore.org/sites/file/dwm.suckmore.org/pull requestes/moveresize/index.md.html.
But there is a good solution to make this example work: Implement the
list start number behavior[1] from the CommonMark spec, so the even
though these items are treated as different lists, each item will get
the intended number. So far, smu always started counting from 0. I'll
do that if nobody voices an opposing opinion.

I've created two PRs[2][3] last September but I didn't receive any
feedback on them. So I didn't see a point in creating less PRs.
