(including the timestamp)
	when creating the commit.

`-c <commit>`::
`--reedit-message=<commit>`::
	Like `-C`, but with `-c` the editor is invoked, so that
	the user can further edit the commit message.

`--fixup=[(amend|reword):]<commit>`::
	Create a new commit which "fixes up" _<commit>_ when applied with
	`git rebase --autosquash`. Plain `--fixup=<commit>` creates a
	"fixup!" commit which changes the content of _<commit>_ but leaves
	its log message untouched. `--fixup=amend:<commit>` is similar but
	creates an "amend!" commit which also replaces the log message of
	_<commit>_ with the log message of the "amend!" commit.
	`--fixup=reword:<commit>` creates an "amend!" commit which
	replaces the log message of _<commit>_ with its own log message
	but makes no changes to the content of _<commit>_.
+
The commit created by plain `--fixup=<commit>` has a title
composed of "fixup!" followed by the title of _<commit>_,
and is recognized specially by `git rebase --autosquash`. The `-m`
option may be used to supplement the log message of the created
commit, but the additional commentary will be thrown away once the
"fixup!" commit is squashed into _<commit>_ by
`git rebase --autosquash`.
+
The commit created by `--fixup=amend:<commit>` is similar but its
title is instead prefixed with "amend!". The log message of
_<commit>_ is copied into the log message of the "amend!" commit and
opened in an editor so it can be refined. When `git rebase
--autosquash` squashes the "amend!" commit into _<commit>_, the
log message of _<commit>_ is replaced by the refined log message
from the "amend!" commit. It is an error for the "amend!" commit's
log message to be empty unless `--allow-empty-message` is
specified.
+
`--fixup=reword:<commit>` is shorthand for `--fixup=amend:<commit>
 --only`. It creates an "amend!" commit with only a log message
(ignoring any changes staged in the index). When squashed by `git
rebase --autosquash`, it replaces the log message of _<commit>_
without making any other changes.
+
Neither "fixup!" nor "amend!" commits change authorship of
_<commit>_ when applied by `git rebase --autosquash`.
See linkgit:git-rebase[1] for details.

`--squash=<commit>`::
	Construct a commit message for use with `git rebase --autosquash`.
	The commit message title is taken from the specified
	commit with a prefix of "squash! ".  Can be used with additional
	commit message options (`-m`/`-c`/`-C`/`-F`). See
	linkgit:git-rebase[1] for details.

`--reset-author`::
	When used with `-C`/`-c`/`--amend` options, or when committing after a
	conflicting cherry-pick, declare that the authorship of the
	resulting commit now belongs to the committer. This also renews
	the author timestamp.

`--short`::
	When doing a dry-run, give the output in the short-format. See
	linkgit:git-status[1] for details. Implies `--dry-run`.

`--branch`::
	Show the branch and tracking info even in short-format.

`--porcelain`::
	When doing a dry-run, give the output in a porcelain-ready
	format. See linkgit:git-status[1] for details. Implies
	`--dry-run`.

`--long`::
	When doing a dry-run, give the output in the long-format.
	Implies `--dry-run`.

`-z`::
`--null`::
	When showing `short` or `porcelain` status output, print the
	filename verbatim and terminate the entries with _NUL_, instead of _LF_.
	If no format is given, implies the `--porcelain` output format.
	Without the `-z` option, filenames with "unusual" characters are
	quoted as explained for the configuration variable `core.quotePath`
	(see linkgit:git-config[1]).

`-F <file>`::
`--file=<file>`::
	Take the commit message from _<file>_.  Use '-' to
	read the message from the standard input.

`--author=<author>`::
	Override the commit author. Specify an explicit author using the
	standard `A U Thor <author@example.com>` format. Otherwise _<author>_
	is assumed to be a pattern and is used to search for an existing
	commit by that author (i.e. `git rev-list --all -i --author=<author>`);
	the commit author is then copied
