I've filed 18464 for it.  I'm not clear from what you said here whether I
should cherry-pick the commit onto the branch myself, or just list it in
the "Maybe" section on the wiki to wait for approval.

I was following the model of the other warning call in that file (and the
end of gdbarch_init_osabi).  It seemed odd to me that it didn't have a
translation wrapper.  But looking around the rest of the code, I see now
that gdbarch_init_osabi is the outlier, and normal usage is to have a
translation wrapper and now trailing newline.  So I've fixed the new call.

I've found a lot of inconsistency as to that in this repository
(and even in this particular file).  I've fixed it to use tabs.

OK.

Below is what I've committed to the trunk.
Can I cherry-pick it to the 7.9 branch too?


Thanks,

I've added a new "Fixes in the GDB 7.9 branch" in case there's
another release.  Please push to the branch and list under "Done".

Go ahead.

I can't seem to figure out how to edit the wiki.  (I only just created my
account there.)  The top line says "Immutable page".

Done.

Ah.  Just like in the glibc wiki, you need to be in the editors
group.  What's your account name?

Yeah, but in glibc I have every kind of privilege and never kept track of
which ones I had or might need. ;-)

Shockingly enough, it's RolandMcGrath. :-)
