Summary 0001841: Example given for lex(1) has rules lacking mandatory action
Description As put lines 101969-101970:
> However, the absence of an action shall not be valid, and the action lex takes in such a condition
> is undefined.

While the noop one-line comment and white space actions given in the example lines 102063-102097 lack an action.
Desired Action Add ; or {} as noop actions, like so:

```
