% The integer part follows much the same pattern, except now it is control

+% We want to make sure that \emph{if} the integer is too long, it pokes out
+% to the left, and at the same time we want to issue exactly one overfull
+% box warning. That is achieved using an explicit test, such that if there
+% is an issue we force the size of the content appropriately. That process
+% will lead to a hit but only for \enquote{defective} input.

-% or re-setting, we do that by recording sizes before and after the change.
