[PATCH v2] doc: patch-id: fix accidental literal blocks

From: Kristoffer Haugsbakk <redacted>

All the final paragraphs on these three options are rendered as
literal blocks. The intent was surely to keep each of them wed to their
respective description list items. But the attempt at maintaining the
indentation level of the block causes each them to be interpreted as a
code block, since code blocks can be represented using indentation.

We need to use list continuation (+) in order to keep them wed to
their blocks.

There is also an unordered list which sandwiches two paragraphs on an
option. We don’t need to do anything about that since it attaches to the
description list item without list continuation (i.e. it is already
correct). But for consistency let’s use list continuation and an open
block on it.

Notes (series):
    v2:
    
    Rewrite the commit message.  Especially with an eye towards
    explaining (and not hedging) why and how things work the way they do; in
    particular that the unordered list is already fine and doesn’t need a
    list continuation.  But let’s go ahead and do it anyway since it doesn’t
    hurt and keeps things more consistent.
    
    Also describe the problem immediately instead of burying the lede/lead
    with “The options here are apparently written ...”.
    
    Also less “the the” mistakes.

    -    The options here are apparently written with the assumption that you

    -    same indentation level.  This is not the the case; you need to use list
    -    continuation (+) for the elements following the first paragraph if you
    -    want to be guaranteed a predictable output

    -    This is kind of subtle since only the last paragraph of each option gets
    -    rendered in an unintended way, namely as literal blocks.  This is easier
    -    to see in the HTML output since the man page output just has a slightly
    -    larger indentation on these paragraphs.
    +    We need to use list continuation (+) in order to keep them wed to
    +    their blocks.
     
    -    Let’s use list continuation throughout, collapse the indentation in
    -    front of all paragraphs except the first one, and wrap the unordered
    -    list in an open block (`--`).
    +    There is also an unordered list which sandwiches two paragraphs on an
    +    option. We don’t need to do anything about that since it attaches to the
    +    description list item without list continuation (i.e. it is already
