fix regex with | and clarify name

[Garfonso]

In a table the | in a regex needs to be escaped, otherwise the part after | is interpreted as new cell (and therefore not displayed at all). Also I added ` to have code tags around the regex which I like a bit more, because regex is kind of code for me (but this is subjective and if you don't want that I can revert it).

Also in telegram the point came up that must not doe mean is not allowed in english and can not be translated word by word. So the old description was wrong there. I changed it quite a bit to also clarify how a user of the results can use the Name part to find states based on function.
