#7 Numbered List can't do more the 9 items

[lewca43]

Using this syntax with HTML output:

(1) some text
(2) some text
(3) some text
(4) some text
(5) some text
(6) some text
(7) some text
(8) some text
(9) some text
(10) some text
(11) some text

Creates 9 sequential bullets, then indents and starts a
new set of
sequential bullets from 1:

1 some text
2 some text
3 some text
4 some text
5 some text
6 some text
7 some text
8 some text
9 some text
1 some text
2 some text

Replacing the 10 and 11 with 9 creates the desired
output, a numbered list from 1 to 11. This is a work
around, but makes the source comment confusing, it has
three "9" bullets.
