a minimal 'binary' markup language

markup.wp

 + title  Markup-file under vim editing 

Text can still remain mostly plain text
with suitable adjustments,
even if the some of the characters
between pre]0x00 - 0x20[ range was
re-purposed for different use.

The pathwp.vim -script is a demonstration piece
and not intended for practical use.
I wish people would spend some time cultivating the idea
before bringing it down into the practice.

Suitability for rich-text editing should be checked
before making use of this format.
A fine environment may require more support than
what is already present in the current description.

To try the code, run this script with
pre:so wp.vim -command,
over the pathmarkup.wp -file.
