Potential bug report: Cannot use ":args" option via Pigeonhole Sieve pipe plugin

Hi all,

Following the instructions noted at
http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe , I am trying to
make use of the Pigeonhole sieve pipe plugin to execute an application with
custom arguments via my test sieve script:

require ["vnd.dovecot.pipe"];
if address :is "to" "test at example.com" {
  pipe :args [ "first-arg", "second-arg" ]
"sieve-pipe-example";
}

I am editing my test sieve script via Mozilla Thunderbird v45.1.1 using the
Sieve email-client addon (v0.2.3h, see
https://github.com/thsmi/sieve#releases and
https://addons.mozilla.org/en-US/thunderbird/addon/sieve/ )

When I attempt to save the example sieve script above, I get the following
error returned by ManageSieve via Mozilla Thunderbird's Sieve addon:

"The script could not be saved:
Sieve mail filter: line 3: error: unknown tagged argument ':args' for
the
pipe command (reported only once at first occurrence).
Sieve mail filter: error: validation failed."

I have setup sieve-pipe-example as follows in my 90-sieve.conf
configuration:

service sieve-pipe-script {
  executable = script /usr/bin/echo
  user = dovenull

  # socket name is program-name in Sieve
  unix_listener sieve-pipe-example {
  }
}

I cannot see where I am going wrong. I have combed through the
specification at
http://hg.rename-it.nl/dovecot-2.2-pigeonhole/raw-file/tip/doc/rfc/spec-bosch-sieve-extprograms.txt
as well as the official Dovecot/Pigeonhole wiki-pages and cannot find a
solution.

If I omit the :args option (and the arguments array), the sieve script
successfully gets accepted by ManageSieve.

Am I encountering a potential bug or am I doing something silly in my test
setup?

Potential bug report: Cannot use ":args" option via Pigeonhole Sieve pipe plugin

It looks like pipe addon specification at
http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/doc/rfc/spec-bosch-sieve-pipe.txt
notes ":args" usage is possible but the implementation source at
https://github.com/dovecot/pigeonhole/blob/master/src/plugins/sieve-extprograms/cmd-pipe.c
shows it was implemented as follows:

pipe "sieve-pipe-example" [ "first-arg",
"second-arg" ];

My test sieve is now working, but I don't understand why I wasn't able
to
use ":args" format noted in the specification document.

The wiki page states that the old pipe plugin is superseded by the 
extprograms plugin. So, this is the correct specification:

https://github.com/dovecot/pigeonhole/blob/master/doc/rfc/spec-bosch-sieve-extprograms.txt#L233
