It seems to me fairly certain that we want this ability to reverse the
direction of a change.
"--reverse" is perhaps too generic a name for the option: we might well want to
reverse other things than the direction of a change, and it seems unlikely that
it will make sense to share a common option name for reversing completely
different things. We should consider a more specific option name like
"--reverse-change".
If the switch will only apply to "-c" then we could make it an alternative to
"-c" rather than an addition to it: e.g. "--reverse-change REVNUM" (possibly
with a short name "-C REVNUM").
Do we want the reversal switch to apply to "-r" as well? That is not necessary
in the basic cases (such as "-r X:Y") but we might decide it is convenient and
consistent. Indeed it might enable some desirable diffs that are not possible
at present: like the reverse of a plain diff (WC against BASE -> BASE against
WC). (Am I right about that? If so, a better solution to that particular
problem might be to introduce a "WORKING" or "WC" revision-keyword.)
Thoughts?
