So, the other way of looking at it - why do we even need an entirely
new option.  Modify --inserts to accept an optional integer value that
defaults to 1 (I'm not sure how tricky dealing with optional option
values is though...).

--inserts-columns implies --inserts but if you want to change the
number of rows you need to specify both (or add the same optional
integer to --inserts-columns)
