Would it?

For Git, we need 'git log -p -n 1', for Hg, 'hg log -p -l 1'. So it's 
hard to do the default implementation.

If you still mean to update the print-log action (which will mean 
updating all backends), I'm okay with that essentially, except we'd 
likely document the extra argument as "also print diffs for each 
revision". It would be weird for it to mean "show diffs INSTEAD of the 
revision log" only in CVS and RCS. But if someone wants to implement it 
that way (with ample commentary), I won't stop them.

I do think this should be better invoked via a new user-visible command, 
though.
