When submitting a revised version of a patch or series, it can be
helpful (to reviewers) to include a summary of changes since the
previous attempt in the form of a range-diff, typically in the cover
letter. However, it is occasionally useful, despite making for a noisy
read, to insert a range-diff into the commentary section of the lone
patch of a 1-patch series.
Therefore, extend "git format-patch --range-diff=<refspec>" to insert a
range-diff into the commentary section of a lone patch rather than
requiring a cover letter.
Implementation note: Generating a range-diff for insertion into the
commentary section of a patch which itself is currently being generated
requires invoking the diffing machinery recursively. However, the
machinery does not (presently) support this since it uses global state.
Consequently, we need to take care to stash away the state of the
in-progress operation while generating the range-diff, and restore it
after.

When generating a range-diff, matching up commits between two version of
a patch series involves heuristics, thus may give unexpected results.
git-range-diff allows tweaking the heuristic via --creation-factor.
Follow suit by accepting --creation-factor in combination with

When submitting a revised a patch series, the --range-diff option embeds
a range-diff in the cover letter showing changes since the previous
version of the patch series. The argument to --range-diff is a simple
revision naming the tip of the previous series, which works fine if the
previous and current versions of the patch series share a common base.
However, it fails if the revision ranges of the old and new versions of
the series are disjoint. To address this shortcoming, extend
--range-diff to also accept an explicit revision range for the previous
series. For example:
git format-patch --cover-letter --range-diff=v1~3..v1 -3 v2

When submitting a revised version of a patch or series, it can be

When generating patches for the rebase command, if the user does
not realize the branch they are rebasing onto is thousands of
commits different, there is no progress indication after initial
rewinding message.
The progress meter as presented in this patch assumes the thousands of
patches to have a fine granularity as well as assuming to require all
the same amount of work/time for each, such that a steady progress bar
is achieved.
We do not want to estimate the time for each patch based e.g.
on their size or number of touched files (or parents) as that is too
expensive for just a progress meter.
This patch allows a progress option to be passed to format-patch
so that the user can be informed the progress of generating the
patch. This option is then used by the rebase command when
calling format-patch.

Maintainers or third party testers may want to know the exact base tree
the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).
The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.
The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name. A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.
Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:
---P---X---Y---Z---A---B---C
With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:
base-commit: P
prerequisite-patch-id: X
prerequisite-patch-id: Y
prerequisite-patch-id: Z

Format-patch generates emails with the "From" address set to the
author of each patch. If you are going to send the emails, however,
you would want to replace the author identity with yours (if they
are not the same), and bump the author identity to an in-body
header.
Normally this is handled by git-send-email, which does the
transformation before sending out the emails. However, some
workflows may not use send-email (e.g., imap-send, or a custom
script which feeds the mbox to a non-git MUA). They could each
implement this feature themselves, but getting it right is
non-trivial (one must canonicalize the identities by reversing any
RFC2047 encoding or RFC822 quoting of the headers, which has caused
many bugs in send-email over the years).
This patch takes a different approach: it teaches format-patch a
"--from" option which handles the ident check and in-body header
while it is writing out the email. It's much simpler to do at this
level (because we haven't done any quoting yet), and any workflow
based on format-patch can easily turn it on.

In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

and the message body starts with the patch description;

The example requires QP encoding in the "Subject:" header intended for
the mailer to give the reader a chance to reflect on that, rather than
being startled by it later. By contrast, in-body "From:" and
