OK, if you say so. ;-) I was thinking more about "in"
meaning after `comment-start'. But yes, I guess that's
what was intended.
If that's the intention then I think it might be clearer
if the index entry were "; outside a comment" or maybe
"; not in a comment".
In any case, that statement is not really true: a semicolon
does not always start a comment in Lisp whenever it is not
within a string or a character constant. There is also the
case of it being escaped in a symbol name. E.g.,
(setq a\;b 42)
(Dunno whether there are additional cases - perhaps not.)
