[Request] [+- ] D12169: simplemerge: remove code for checking binary input now that callers do it

REVISION SUMMARY
  The callers now do the checking for binary inputs and handle warnings
  and/or errors, so we can remove that code from the low-level
  `simplemerge` module now. After this patch we just raise an error
  unless the caller told us to allow binary inputs.
