Message #5 received at submit <at> emacsbugs.donarmstrong.com (full text, mbox):
Hello!
When executing describe-text-properties on some character a *Help*
buffer is created or updated with some text content, for example:
Text content at position 234:
There is an overlay here:
From 234 to 246
font-lock-face comint-highlight-prompt
There are text properties here:
field output
fontified t
front-sticky (field inhibit-line-move-field-capture)
inhibit-line-move-field-capture t
rear-nonsticky t
Similarly C-u C-x = produces a *Help* buffer without [back] and/or
[forward] buttons. No matter how often I repeat these two commands,
no button is created. But when I run describe-variable or describe-
function and a [back] button is created by them in *Help* buffer,
then describe-text-properties (or C-u C-x =) kind of inherit this
feature and create *Help* buffers with a [back] button.
Shouldn't all functions which overwrite the previous contents of
*Help* buffer also insert that [back] button?

Yes. I've installed a change which should fix it for
describe-text-properties and describe-char. Please confirm that it
solves your problems,
Stefan

Yes, I can confirm that describe-text-properties now works as
describe-function or describe-variable.
But – there seem to be other describe-<whatever> functions which do
not work like these. Some of these functions produce a [back] key
only when they are repeated (describe-character-set for example,
describe-categories, describe-face, describe-fontset) and not when
they overwrite the contents of the *Help* buffer. Some never seem to
create this navigation element:
describe-bindings-internal
describe-buffer-case-table
describe-coding-system
describe-current-coding-system
describe-current-display-table
describe-font
The functions describe-minor-mode-from-indicator and describe-minor-
mode do not show any possible completions...

I tried the commands here in Emacs 28, and they all seemed to produce a
[back] button for me, so I'm going to go ahead and guess that this has
been fixed in the decade since it was reported, and I'm closing this bug
report.
