I broke this in r1702 where I enabled avoidance of the verification step if
we did not modify anything in the erase/write step. The problem is that
all_skipped is initialized to true and hence it would only ever verify if
there have been changes noted in the erase/write step. This obviously
breaks the verification operation (-v/--verify) because there we never
enter the erase/write loop.
The better alternative would be to enable (the implicit) verification
in the write loop and not in cli_classic.c. This would require a bigger
change due to the existance of dont_verify_it. Eventually this is the
right thing to do but not so shortly before a release.
