This patch is in next as c1565b6f7b53ea1ea3e757538832e12d7d13d949. It
breaks one of my scripts that I use to semi-automatically determine
recipents for patch series.

It works as follows:

        $ batch-add-recipents 
audin-patch-v1/0001-ASoC-meson-HACK-let-AIU-export-its-clocks-through-cl.patch
        #!/bin/sh

        addrecipent \
        -t "Rob Herring <r...@kernel.org>" $(: maintainer:OPEN FIRMWARE AND 
FLATTENED DEVICE TREE BINDINGS) \
        -t "Krzysztof Kozlowski <krzk...@kernel.org>" $(: maintainer:OPEN 
FIRMWARE AND FLATTENED DEVICE TREE BINDINGS) \
        -t "Conor Dooley <conor...@kernel.org>" $(: maintainer:OPEN FIRMWARE

        -t "Neil Armstrong <neil.armstr...@linaro.org>" $(:

audin-patch-v1/0001-ASoC-meson-HACK-let-AIU-export-its-clocks-through-cl.patch

the output is usually redirected to a file that I edit before running
it. The additional line in the output of

        scripts/get_maintainer.pl 
audin-patch-v1/0001-ASoC-meson-HACK-let-AIU-export-its-clocks-through-cl.patch

with your change breaks that script.

#regzbot introduced: c1565b6f7b53ea1ea3e757538832e12d7d13d949
#regzbot title: get_maintainer's subsystem status output breaks custom script

I can cope with it, but still wanted to let you know that people use
get_maintainers for `git --cc-cmd`-like usages without --norolestats.

Given that I use scripts/get_maintainer.pl from the tree I currently
work at and sometimes that is based on next, sometimes on linus/master
or -rc1 and sometimes even older trees (e.g. stable), the introduced
`--no-substatus` option doesn't help me because when run from a tree
without your change I get:

        $ scripts/get_maintainer.pl --no-substatus 
audin-patch-v1/0001-ASoC-meson-HACK-let-AIU-export-its-clocks-through-cl.patch
        Unknown option: no-substatus
        scripts/get_maintainer.pl: invalid argument - use --help if necessary

so I cannot use that option easily until all the trees I care about get
your change. :-\

Uwe
