Figure captions are now numbered 1, 2, 3, ... The format in
the caption is "Figure 1: <caption>" and so on.
This is necessary in order for libreoffice to generate an
Illustration Index (Table of Figures) for included figures.
This patch eliminates the large gap we used to have between
bullet and text, and also ensures that numbers in numbered
lists will be right-aligned.
Closes#4385.
This is now the default for pandoc's Markdown.
It allows whitespace between the two parts of a
reference link: e.g.
[a] [b]
[b]: url
This is now forbidden by default.
Closes#2602.
This avoids overly narrow labels for ordered lists with
() delimiters.
However, arguably it creates overly wide labels for bullets.
Also, lists now start flush with the margin, rather than
indented.
Fixes#2421.
