Do not print column numbers in diagnostic messages. This may be
necessary if processing the diagnostic messages with a program that
does not understand the column numbers.
The default behaviour of sprase, to print the column numbers, is
left as is by this patch.

This patch applies to the "-chrisl" tree. It would need a minor
modification in the sparse.1 part to apply to Josh's tree as
well.
