diff: change --inverse to --reverse

This fixes an incompatibility with patch(1), which also uses --reverse
for reversed diffs. The --inverse flag was added in 3f522d2fa633. That
name was chosen over --reverse since it was thought that --reverse
would make --rev ambiguous.

It turns out that both flags can co-exist, with the cost that --rev
can no longer be shortened to --r and --re. Since one can always use
the short -r option, this is not a real problem.
