"arbitrary comparison function" that compares 2 texts and reports what
is 'different' is certainly possible, but outside the scope of what most
people actually care to do from the command-line. --ignore-whitespace on
the other hand, is asked for reasonably often.

Also, --ignore-whitespace would be well defined and cacheable. I don't
even trust that "arbitrary comparison function" is stable. (eg x != y,
but y == x.)
