That article gives a very good background on how you can use perl,
instead of tr, as the external filter to accomplish your task. It also
sounds like you have the start of a vimrc parser to use as a
configuration file for your script.

For readability reasons, I would not write it as a single giant RE,
however, but a series of very small REs applying the rules in order.

Perl is a language written by an amateur linguist, so it seems to
attract people with that mindset.
