be0ef6fcd2 format-patch: add commitListFormat config
Using "--cover-letter" we can tell format-patch to generate a cover
letter, in this cover letter there's a list of commits included in the
patch series and the format is specified by the "--cover-letter-format"
option. Would be useful if this format could be configured from the
config file instead of always needing to pass it from the command line.

Teach format-patch how to read the format spec for the cover letter from
the config files. The variable it should look for is called
format.commitListFormat.

Possible values:
  - commitListFormat is set but no string is passed: it will default to
    "[%(count)/%(total)] %s"

  - if a string is passed: will use it as a format spec. Note that this
    is either "shortlog" or a format spec prefixed by "log:"
    e.g."log:%s (%an)"

  - if commitListFormat is not set: it will default to the shortlog
    format.

6005932d95 format-patch: add ability to use alt cover format
Often when sending patch series there's a need to clarify to the
reviewer what's the purpose of said series, since it might be difficult
to understand it from reading the commits messages one by one.

"git format-patch" provides the useful "--cover-letter" flag to declare
if we want it to generate a template for us to use. By default it will
generate a "git shortlog" of the changes, which developers find less
useful than they'd like, mainly because the shortlog groups commits by
author, and gives no obvious chronological order.

Give format-patch the ability to specify an alternative format spec
through the "--cover-letter-format" option. This option either takes
"shortlog", which is the current format, or a format spec prefixed with
"log:".

Example:
    git format-patch --cover-letter \
        --cover-letter-format="log:[%(count)/%(total)] %s (%an)" HEAD~3

    [1/3] this is a commit summary (Mirko Faina)
    [2/3] this is another commit summary (Mirko Faina)

As of now format-patch allows generation of a template cover letter for

Move shortlog summary code generation to its own function. This is done
in preparation to other patches where we enable the user to format the
commit list using thier own format string.

9ccd9e6fca pretty.c: add %(count) and %(total) placeholders
In many commands we can customize the output through the "--format" or
the "--pretty" options. This patch adds two new placeholders used mainly
when there's a range of commits that we want to show.

Currently these two placeholders are not usable as they're coupled with
the rev_info->nr and rev_info->total fields, fields that are used only
by the format-patch numbered email subjects.

Teach repo_format_commit_message() the %(count) and %(total)
placeholders.

a190f01f57 Documentation: extend guidance for submitting patches
Before submitting patches on the mailing list, it is often a good idea
to check for previous related discussions or if similar work is already
in progress. This enables better coordination amongst contributors and
could avoid duplicating work.

Additionally, it is often recommended to give reviewers some time to
reply to a patch series before sending new versions. This helps collect
broader feedback and reduces unnecessary churn from rapid rerolls.

Document this guidance in "Documentation/SubmittingPatches" accordingly.

e4f9d6b0ab rebase: support --trailer
Add a new --trailer=<trailer> option to git rebase to append trailer
lines to each rewritten commit message (merge backend only).

Because the apply backend does not provide a commit-message filter,
reject --trailer when --apply is in effect and require the merge backend
instead.

This option implies --force-rebase so that fast-forwarded commits are
also rewritten. Validate trailer arguments early to avoid starting an
interactive rebase with invalid input.

Add integration tests covering error paths and trailer insertion across
non-interactive and interactive rebases.

5e148696bf commit, tag: parse --trailer with OPT_STRVEC
Now that amend_file_with_trailers() expects raw trailer lines, do not
store argv-style "--trailer=<trailer>" strings in git commit and git
tag.

Parse --trailer using OPT_STRVEC so trailer_args contains only the
trailer value, and drop the temporary prefix stripping in
amend_file_with_trailers().
