%% \widelabel is defined for use when the width of the enumsentence or
%% eenumsentence number is wider than 20pt (default labelwidth).  As a
%% rule of thumb if your enumerated sentences are only 1 or 2 digit
%% you don't need to worry.  At 3 digits, set \widelabel to 2.78pt at 4
%% digits set to 7.78pt.
