please be explicit as to what 0 and 1 mean. in general, a process exit code of 0
means success and non-zero means failure, but it looks like the implementation
returns 1 for has-been-accepted and 0 for not-been-accepted (in contrast to this
comment's implied 0=accepted, 1=not accepted).

Done; made comment explicit, and returning E_FAIL on error.
