I'm not talking about help, I'm only talking about the manual.  The
bug report was about inconsistencies in the manual.  At least that's
how I perceived it, and that's the only issue I set out to fix.

Which part is unclear?

See the guidelines I used to decide on names and capitalization, I
tried to explain why I choose this or that convention.

If that's the issue, then (a) it was nowhere clear from your original
bug report, and (b) I will have nothing to do with it, sorry.  I don't
care enough about it to work on that.

I only fixed inconsistencies in the manual, without any relation to
what Emacs says in help mode.

Perhaps it could be nice (although it never bothered me), but I think
it's close to impossible now, due to various historical reasons.  In
any case, I'm not going to do anything about this, someone else will
have to step forward.  I found your complaint about inconsistencies in
the manual justified, and I fixed that; my job here is now done.
