Right, let's just stay with reST:

 http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html

We already have some special kernel-doc additions e.g. for highlighting,
cross referencing and "DOC:":

 https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html#how-to-format-kernel-doc-comments

But we should not break with reST fundamentals.

There are other plain text markups on the market, I would remember Markdown as one.
They all come with markup rules (syntax), to make text parseable. Mauro brought the
example with lists and colons. In ReST, the "::" introduce an indented literal block,
which can be used for code block examples or a small ASCII art.

FWIW: at docutils there is also a (slow ongoing) discussion about reST syntax
alternatives  

 http://docutils.sourceforge.net/docs/dev/rst/alternatives.html

may the syntax discussion is better placed there?
