--- Comment #1 from Abel Braaksma <abel.braaksma@xs4all.nl> ---
Hmm, reading more, I see that we say in the same section:

    "The sub-expressions are numbered according to the position of the opening 
    parenthesis in left-to-right order within the top-level regular
expression:"

but searching for "top-level regular expression" does not yield any results.
What is it? Does this include or exclude nested expressions? Since each paren
can start a new regex, this does not seem to make sense.

Should it perhaps mean "when not inside a character class"?
