For small patchsets (and recipients list) I recommend:
https://github.com/krzk/tools/blob/master/linux/.bash_aliases_linux#L91

For bigger patchsets - Rob's sendemail identity could work:
https://lore.kernel.org/all/CAL_JsqLubWBr2W3xZPsuPLOGav7CFgBdH=aCfT22F_m0_cx3cQ@mail.gmail.com/
but cover letter has to be treated separately.

Anyway, it is not the case here. This is small patchset and the
submitter should run get_maintainers.pl on *the patchset*, not on one
chosen file. Running it one one file, ignoring maintainers of all other
patches, does not make sense. There is nothing to fix in
get_maintainers.pl. I believe our docs are also correct here.

Best regards,
Krzysztof
