This is uncomfortably big at this phase of the release cycle, but
thanks anyway.

Because I didn't want to review this patch only to spot silly
formatting mistakes that may break the documentation build (which I
didn't find any), I looked the entire files the patch touches, and
many of the comments below ended up being suggestions for a
follow-up work for people who would want to pick low-hanging fruits.

Hint, hint.

There however are a few things that should have been in this patch,
though.  I'll attach what I'd queue as "SQUASH???" on top of this
patch at the bottom.

OK.

We still have two separate entries for "--scissors/--no-scissors"
and "--utf8/--no-utf8" pairs in the description text.  Do they want
to get united somehow?

OK.

We have "--no-hardlinks" without "--hardlinks".  Does the parser
accept "--no-no-hardlinks"?  If so, we may want to error it out.

I would omit the options "--no-hardlinks" and "--shared", and added
"--local={link,copy,shared}" instead, as these two options only make
sense when cloning from a local repository, if I were doing the UI
from scratch today.

OK.

The SYNOPSIS section begins like this:

    SYNOPSIS
    --------
    [verse]
    'git config' [<file-option>] [type] [-z|--null] name [value [value_regex]]
    ...

Other parts of this patch seems to want to have SPs around vertical
bars that shows choices, so "[-z | --null]" would be necessary as a
follow-up to bring more consistency.

The placeholders like "type", "name", "value", etc. are not inside
<angle-brackets>, which may want to be fixed as well.

It is unclear what "<file-option>" is.  A few paragraphs in the
DESCRIPTION section talk about --system/global/etc.; there should be
a sentence there to mention that exact term <file-option> to help
the reader make a connection, just like the paragraph that talks
about "type" uses that word to make it clear the word in SYNOPSIS is
about things like --int/bool/path.

You can say "--inetd".  Only when you do not say "--inetd", you can
use "--listen", "--port", etc.  Further, only when you say "--user",
you can also say "--group".  OK.

As this is governed by [verse], it would be more helpful to show
that logic not just with the nesting of [], but make it stand out
with a line break, perhaps like:

        [--inetd |
         [--listen=<host>] [--port=<n>]
         [--user=<user> [--group=<group>]]]

(I do not mind to see a single line for the second and third lines).

OK.

By the way, this is missing from SYNOPSIS, unlike all the other
options to this command.

OK.

"--no-no-data"?  If so, we may want to error it out.

    SQUASH???

    Update the overlong SYNOPSIS section for git-daemon. As the patch
    adds SPs around vertical bars for [choice1 | choice2], match the
    line it touches in git-mergetool.txt to also do that.
