Well, my thinking for the initial (restricted; you couldn't say 'git
checkout -p HEAD~14') version went something like this: 'reset -p'
should be the opposite of 'add -p', so it offers the same hunks with
the question "Reset?". Then 'checkout -p' should somehow follow suit,
but asked "Discard?" (IIRC I even had it in all caps).
I'm not 100% happy with your suggested forward patches strategy
because I think (particularly for people with colors enabled, and I
suspect we all have), it's less confusing "my" way if they go through
'add -p' and suddenly think "oops, mistake, I need to reset that": it
is much easier for the (at least for my) eye to find the same hunk
again if it is really 100% the same. Probably we would have to change
the verb to "discard" again, though.
OTOH this does become rather weird once you specify anything other
than HEAD. And while we could of course switch the approach if the
user does that, and hope that he'll understand on the grounds that
it's an advanced usage, I'm not sure switching is a good idea in
general.
