We now have Section 15.5.10, (five digits + two periods).
Default of the book class can not afford that much digits in
subsection count.
Increase width parameters to accomodate it.
Also, as for -sf builds, the Helvetica clone font needs slightly
wider spaces in the "em" unit. Add settings for -sf builds.
Mention default widths in the comment block for future reference.
