find: tweak error message
big find: find: missing argument to `-exec' we now say find: -exec requires an argument instead of the cryptic message we emitted previously. Additional benefit is that it's now 23 bytes smaller. Add TODO to add '-exec {} +' support Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
