#
# markdown2html.py — simple Markdown-to-HTML converter for use with Mutt
#
# Mutt recently learnt [how to compose `multipart/alternative`
# emails][1]. This script assumes a message has been composed using Markdown
# (with a lot of pandoc extensions enabled), and translates it to `text/html`
# for Mutt to tie into such a `multipart/alternative` message.
#
# [1]: https://gitlab.com/muttmua/mutt/commit/0e566a03725b4ad789aa6ac1d17cdf7bf4e7e354)
#
# Configuration:
#   muttrc:
#     set send_multipart_alternative=yes
#     set send_multipart_alternative_filter=/path/to/markdown2html.py
#
# Optionally, Custom CSS styles will be read from `~/.mutt/markdown2html.css`,
# if present.
#
# Requirements:
#   - python3
#   - PyPandoc (and pandoc installed, or downloaded)
#   - Pynliner
#
# Optional:
#   - Pygments, if installed, then syntax highlighting is enabled
#
# Latest version:
#   https://git.madduck.net/etc/mutt.git/blob_plain/HEAD:/.mutt/markdown2html

isn't really properly handled by Markdown, so let's do our best to
    identify the individual elements, and mark them, using a syntax similar to
    what pandoc uses already in some cases. As pandoc won't actually use these
    data (yet?), we call `self._reformat_quotes` later to use these markers
    to slap the appropriate classes on the HTML tags.
