Can we directly tighten the "trailing..." part, instead of having to
add an extra long sentence ...

... like this as an attempt to clarify?

    Leading whitespace characters before and after 'name =', and the
    remainder of the line after the first comment character '#' or
    ';', are removed, and then trailing whitespace characters at the
    end of the line are discarded.

By the way, if a run of whitespace characters are enclosed in double
quotes, they cannot be trailing at the end of the line, as the
closing double quote is not a whitespace character, so it is out of
place to talk about quoted string in the context of trailing blank
removal.  The unquoting would want to be discussed separately.

Good.

Thanks for working on this topic.
