I'm not sure if it's a good idea to read --status-fd from stdout for
exactly the reason you describe.

In Enigmail I read it on a separate file descriptor, and check the
results at the end of the process, before displaying the data to the
user. This way, I can count the number of PLAINTEXT occurrences, and if
needed I can split the output according to the PLAINTEXT_LENGTH fields
(at least I hope that this is reliable information).
