Sure, the result is formally correct.  It's just counter-intuitive.

Normally when I say 'q' in the "*Help*" buffer, I bury it.  But here,
'q' buries two buffers.

Thanks for explaining the motivation behind that feature.

I'm fine with doing a less invasive change: treat 'q' as a special
case in Info-summary.  Many users are hardwired to press 'q' to make a
"*Help*" buffer go away.

However, there is an inconsistency between modes; in view-mode and
special-mode, '?' is bound to describe-major-mode.

Would it be worth it to be more consistent?  In other words, doing one of:

(a) make 'Info-summary' into a general help command and use it in more
places, or
(b) deprecate 'Info-summary' in favour of 'describe-mode'.

It seems to me that _if_ we think the 'Info-summary' behaviour is
useful, we would want to ensure more modes can benefit from it.  Or,
to put it another way, I don't see why it would be uniquely useful to
Info-mode -- it should be useful either in many more modes or nowhere.
I haven't formed a strong opinion on this, but it would be interesting
to hear what people think.
