[PATCH] Fix gpg output parsing Use «foreach» instead of «while» to traverse the GnuPG output array, otherwise the topic variable never gets initialized, and the «while» continuously evaluates the array in boolean context and we get into infinite loops.
With GnuPG the infinite loop currently never triggers because it does not output anything on stdout. But with the Sequoia GnuPG Chameleon it outputs the original contents being verified (which is a divergence that should probably be fixed upstream).
Force the output to stdout instead of stderr so that we can parse it, and update the parser to match on current output lines. Although ideally the parser should be switched to try to use one of the machine parseable outputs such as --with-colons, otherwise there is no guarantee this will not change again in the future, but this is the simplest minimal change.
