the gdb docs are little unclear:
https://sourceware.org/gdb/wiki/Internals%20Releasing-GDB

it focuses on the gdb/ subdir.  that makes sense -- the gdb branch is meant
for releasing gdb, and most bugfixes will be in that directory.

but what about commits outside of gdb/ ?  does the gdb branch maintainer
have to approve each one ?  like something in bfd/ or libctf/ or sim/.
or is it good enough that it's already been approved & merged into master,
and the flow is more interested folks post a [committed] notification to
the list when they cherry-pick back ?
