Don't mention git reset --hard in the documentation for git stash save.
It's an implementation detail that doesn't matter to the end user and
thus shouldn't be exposed to them.  In addition it's not quite true for
git stash -p, and will not be true when a filename argument to limit the
stash to a few files is introduced.

The documentation gives an example of the submodule foreach
command that uses both backticks and single-quotes. We stick
the whole thing inside "+" markers to make it monospace, but
the inside punctuation still needs escaping. We handle the
backticks with "{backtick}", and use backslash-escaping for
the single-quotes.

But we missed the escaping on the second quote. Fortunately,
asciidoc renders this unbalanced quote as we want (showing
the quote), but asciidoctor does not. We could fix it by
adding the missing backslash.

However, let's take a step back. Even when rendered
correctly, it's hard to read a long command stuck into the
middle of a paragraph, and the important punctuation is hard
to notice. Let's instead bump it into its own single-line
code block. That makes both the source and the rendered
result more readable, and as a bonus we don't have to worry
about quoting at all.

Each of these options is missing the closing single-quote on

In a9e38359 we taught git-p4 a way to re-encode path names from what
was used in Perforce to UTF-8. This path re-encoding worked properly for
"added" paths. "Removed" paths were not re-encoded and therefore
different from the "added" paths. Consequently, these files were not
removed in a git-p4 cloned Git repository because the path names did not
match.

Fix this by moving the re-encoding to a place that affects "added" and
"removed" paths. Add a test to demonstrate the issue.

When using non-builtin protocols relying on a transport helper
(such as http), push options are not propagated to the helper.

The user could ask for push options and a push would seemingly succeed,
but the push options would never be transported to the server,
misleading the users expectation.

Fix this by propagating the push options to the transport helper.

This is only addressing the first issue of
   (1) the helper protocol does not propagate push-option
   (2) the http helper is not prepared to handle push-option

Once we fix (2), the http transport helper can make use of push options
as well, but that happens as a follow up. (1) is a bug fix, whereas (2)
is a feature, which is why we only do (1) here.

If you run "git log --graph --name-only", the pathnames are
not indented to go along with their matching commits (unlike
all of the other diff formats). We need to output the line
prefix for each item before writing it.

The tests cover both --name-status and --name-only. The
former actually gets this right already, because it builds
on the --raw format functions. It's only --name-only which
uses its own code (and this fix mirrors the code in
diff_flush_raw()).

Note that the tests don't follow our usual style of setting
up the "expect" output inside the test block. This matches
the surrounding style, but more importantly it is easier to
read: we don't have to worry about embedded single-quotes,
and the leading indentation is more obvious.

detached HEAD in --all - 2009-01-16).

Even though that commit is about detached HEAD, as Jeff pointed out,
always adding HEAD in that case may have subtle differences with
--source or --exclude. So the document mentions nothing about the
detached-ness.

Before 7176a314 (index-pack: complain when --stdin is used outside of a
