I meant: when there's no diff utility available.
Of course, if there's a PHP-based diff available, everything in this
subthread is moot ;-)

If there are simultaneous edits, there will be some punishment for all
but one of the simultaneous authors. It's just a question whom to punish...

Sure. OTOH it would be too easy to simply save your own changes and
overwrite those of the other people. Besides, if there's no good diff
available, it's easier to spot your own changes than those of other
people, let alone reapply them - IOW the temptation to clobber those
other changes will be quite high.
