bug#27230: eldoc doc

I'm confused about how the command `define-globalized-minor-mode'
defines will handle buffers that already have the minor mode turned
on.  Say buffers A and B have simple `eldoc-mode' switched on, and
buffers C and D don't (and global-eldoc-mode is off).  If I then
switch global-eldoc-mode on, is every buffer's value of eldoc-mode
now /on/, or do the values get toggled instead (leaving A and B off, C
and D on)?  And after that, if I toggle global-eldoc-mode off again,
are the previous values remembered and restored, or does every buffer
now have eldoc-mode switched off?

Thanks for your help with this. I've probably missed a paragraph in the docs somewhere.

In 25.2, none of these lines are needed.  Maybe
these lines could be replaced with a mention of global-eldoc-mode,
and how the "globalized" minor mode and eldoc-mode interact (not sure
how they do).

Do you mean that how define-globalized-minor-mode works is unclear to you, or some aspects of how it applies to eldoc-mode?

Also, most of the functions in eldoc have no docstring (seems ironic).
Would there be any interest in a patch to fix that?
