Previously, each indent of 2 spaces would introduce a new indentation level.
This lead to a confusing output in a variety of situations,
especially in changelog style commit messages.
Now, new indent levels are only introduced when they need to be,
i.e. when there's actually a new indented list or paragraph:
{{{
* first level
* second level
- third level
First level
Second level
}}}
Note that a tab character is converted to 8 space characters
before computing the indentation level.
In addition, lists can now also be started using "-" (as this is commonly found
in changelogs as well).
There will be a follow-up changeset focused on the interaction between lists and quotes.
