helpers: introduce ascii preserving visual markup of *bold*

No matter what kind of text (code and markup) is parsed, it will at most have
slightly odd styling. Nothing will be lost and it can be copy-pasted correctly.

Other kinds of markup (like _underline_ and /italic/) has also been considered
... but they will too often interfere with valid code and command snippets.
