Das Gendersternchen funktioniert nicht gut zusammen mit Markdown. Folgender
Regexp liefert ein Preprocessing, was es ermöglicht, ohne einen anderen
Markdown-Dialekt zu wählen (Regulärer Ausdruck in Python):

> for x in ["Gender*nnen","foo *bar* baz", "foo *bar*baz", "Und *das* ist wirklich Mensch*nnen *und* toll."]:
>      print(re.sub(r"(^|\s)(\w+)\*([^.\s]*\w+)($|\s)", r"\1\2\*\3\4", x))

Gender\*nnen
foo *bar* baz
foo *bar*baz

# A python3 script to read an mbox file (extension to Maildir is trivial thanks to
# mailbox module) and writes out certain headers as CSV file.
# On large mbox files (say 5GB) it is slow because... it's Python.
# The script deals with some cornercases (encoding, newlines, ...) which I found in
# 100K emails. Otherwise, the builtin python mail libraries provide robustness.
#
# It processes roughly 110K (5GB mbox) mails in 2:35mins on my laptop and produces
# a 19MB CSV file.

 * A Firefox Quantum ViewSourceWith replacement for Windows.
 * When compiled, this behaves like an editor, i.e. you call

 * the real file to open.
 *
 * Todo:
 *
 *  1) Read editor path from INI file with GetPrivateProfileString
 *  2) hide the console when opening the real notepad
