Subject: bug#44503: 27.1; image-scroll-up and image-scroll-down
Date: Sat, 7 Nov 2020 09:16:22 -0600 [thread overview]
Message-ID: <47686.12087.468202.24486@gargle.gargle.HOWL> (raw)
My understanding of the doc strings of image-scroll-up and
image-scroll-down is that the argument N should be a number, nil, or
`-'." However, these commands use (interactive "P") with
prefix-numeric-value inside the body of these commands. I suggest
to document this behavior. (I guess it is not very clean to use
prefix-numeric-value inside the body of these commands. But
changing this behavior likely will break existing code that uses
these commands.)
I realized this when I looked at doc-view's scrolling commands
doc-view-scroll-up-or-next-page and
doc-view-scroll-down-or-previous-page
that likewise use (interactive "P"), contrary, to what the
docstrings of these commands say, and I was surprised that this
gives a meaningful behavior. So these docstrings probably should be
updated, too.
