* DocPara will compare this value (previous para's indent) with the
current indentation. If indent > margin + 2, it will add 4 spaces
to the first line (see below for why I'm adding 4 spaces).
I just realized that this would cause a problem with nested lists. A
solution here is to indent multi-paragraph lists to 4 spaces in the docs
itself, so that docwriter is freed from the responsibility of keeping track of
the spaces.
If this is done, docwriter will only check if
indentation(current paragraph) >= 4 + indentation(parent paragraph).
The parent paragraph is the closest outer paragraph before the first
4-space indented paragraph started.
Therefore for convenience, I'm keeping the required indentation at 3
spaces, and adding 4 wherever there are 3 or more.
This becomes invalid as the responsibility of 4-space indentation is
now on the source.
See the attached screenshots, for an idea of how this will work.
