Patch to 8.3.0-T2A/dig.c

[Andris Kalnozols]

Here's a patch to dig.c that came with 8.3.0-T2A.
It fixes the following:

  * Incremented the version string to 8.4 to differentiate this
    DNSSEC-capable version of dig from the previous non-DNSSEC
    versions.

  * Found an instance of an unflushed error message that would
    cause a reader of dig's stdout to block if dig's batch file
    was a pipe.
