[texhax] Memoir class ToC starts arabic numbering one page too late

[M. Fioretti]

Greetings,

the template below produce an unforeseen (for me) effect: Title,
author and Toc take 3.5 pages. However, only the first three pages are
numbered i, ii, iii. The 4th page, instead of being numbered "iv", is
where the arabic numbering starts, that is it is numbered "1". Why? I
thought that the options in that template would make arabic numbering
start from the fifth page.

Note: if I uncomment the \pagebreak statement, arabic numbering does
start from the fifth page, but the ToC entries are spread at equal
intervals in the fourth page, to fill it top to bottom (which is ugly,
isn't it? I'd like to have the same spacing of the previous ToC pages
there)

Thank you in advance,

	Marco
