 GNU cmp should have missing '--recursive' option.

[Message part 1 (text/plain, inline)]

These maybe 2 different bugs, but they both deal with recursion, so both are
reported here.


(1)
Hard-disk-drives, Solid-state-drives, flash media, etc. might have errors in
certain blocks/sectors.

But this does not mean that diff, when running in '--recursive' mode, should
stop after encountering the first "input/output error".

At the very least, there should be a '--continue-on-error' option, to make diff
proceed to the next file comparison(s) when operating in '--recursive' mode.


(2)
cmp does not have a '--recursive' option analagous to diff - and it should - as
there might be a need to compare 2 directories of binary files.
