Well dealing with remainders would be an argument for implementing
--number=L/N as it could distribute lines more evenly.

I.e. --number=L/N would be like l/N, but it would
try harder to evenly distribute lines,
by identifying the number of lines up front,
and determining which chunks would get an extra line
to cater for the remainders.
