Subject: bug#4979: 23.1.50; describe-text-properties produces *Help* buffer without back/forward buttons
Date: Thu, 19 Nov 2009 22:23:31 +0100 [thread overview]
Message-ID: <DD61943F-857A-451A-8F87-A9A7E3CFE671@Freenet.DE> (raw)
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?
