You should use either context (-c) or unified (-u) format. The
advantage of these over the traditional and ed formats is that the
patch can still be applied if the line numbers have changed (e.g. due
to other parts of the file being changed). Also, the context and
unified formats are easier to read than the others.
The choice between context and unified formats is largely a matter of
taste, although more people seem to prefer unified than prefer
context.

Yep.
