The caller of parse_mail() and parse_mail_rebase() is not prepared
to see an error code in the returned value from these function,
which are to return a boolean telling the caller to skip or use the
patch file. At least the caller needs to notice negative return and
made to die/exit(128), instead of silently skipping a corrupt or
unopenable patch, no? Otherwise this will change the behaviour.
