Subject: [PATCH -next] docs: vm/page_owner: Tweak literal block in STANDARD FORMAT SPECIFIERS

A semantic conflict between commit 5603f9bdea68 ("docs: vm/page_owner:
use literal blocks for param description") and a change queued for v5.19
authored by Jiajian Ye ("tools/vm/page_owner_sort.c: support sorting
blocks by multiple keys") results in a warning from "make htmldocs"
saying:

[...]/vm/page_owner.rst:176: WARNING: Literal block expected; none found.

This is because a literal block in ReST ends at a line which has the
same indent as the paragraph preceding it. In this case the one with
no indent.

Indent the two "For --xxxx option:" lines by two columns and make the
whole section a literal block.

While at it, fix indents by white spaces of "ator" keys.

Hi Andrew,

This is kind of a follow-up fix of commit 5603f9bdea68 ("docs:
vm/page_owner: use literal blocks for param description"), which I
sent the other day [1] as a fix against v5.18-rc1 and merged into
v5.18-rc5.

The fix in mainline results in a minor semantic conflict with your
tree destined for v5.19, and causes another warning from "make html".
Shenghong Han submitted a patch around the key lists using the ReST
table construct [2] based on Haowen Bai's earlier attempt [3], but
it seems the effort has stalled.

Hence I'm submitting this patch against your tree as a resolution
of the semantic conflict, with additional indent fixes as were done
in [2].

Note: By making the whole section a literal block, excessive inline
literal markers around --sort and --curl options can be avoided.

For example, in a normal ReST paragraph,

For --sort option:

will be converted by Sphinx to

For –sort option:

in HTML, where the "–" is an "endash" symbol.

Such conversions could be prevented by putting inline literal markers
around:

For ``--sort`` option:

However, it would degrade the readability of the .rst file as
plain-text. In this particular case, making the whole section
a literal block should be a better option, at long as the section
consists only of those key lists.

Thanks, Akira
