The yyyy-mm-dd (actually \d\d\d\d-\d\d-\d\d) for a bit more restrictive (and self-documentative) than the \w\w\w\w-... that used to be there and UNRELEASED so that developers can test the latest NEWS converted to mdwn format before submitting NEWS patches.

# Markdown doc specifies that list item may have paragraphs if those

# implementations.
|

# In our NEWS case this problem exists in release 0.6 documentation.

# It can be avoided by removing 2 leading spaces in lines that are not
|
|
# list items and requiring all that indents are 0, 2, and 4+ (to make
|
|
# regexp below work).

# Nested lists are supported but one needs to be more careful with
|
|
# markup there (as the hack below works only on first level).
