+--fixup=[(amend|reword):]<commit>::
+ Construct a new commit for use with `rebase --autosquash`,
+ which fixes the specified commit. The plain form
+ `--fixup=<commit>` creates a "fixup!" commit, that allows
+ to fixup only the content of the specified commit and leave
+ it's commit log message untouched. When used with `amend:`
+ or `reword:`, it creates "amend!" commit that is like "fixup!"
+ commit but it allows to fixup both the content and the commit
+ log message of the specified commit. The commit log message of
+ the specified commit is fixed implicitly by replacing it with
+ the "amend!" commit's message body upon `rebase --autosquash`.
++
+The resulting "fixup!" commit message will be the subject line
+from the specified commit with a prefix of "fixup!". Can be used
+with additional commit message option `-m`.
++
+The `--fixup=amend:<commit>` form creates an "amend!" commit where
+its commit message subject will be the subject line from the
+specified commit with a prefix of "amend!" and the message body
+will be commit log message of the specified commit. It also invokes
+an editor seeded with the log message of the "amend!" commit to
+allow to edit further. It refuses to create "amend!" commit if it's
+commit message body is empty unless used with the
+`--allow-empty-message` option.
++
+The `--fixup=reword:<commit>` aliases `--fixup=amend:<commit> --only`
+and it also creates an "amend!" commit, but here it records the same
+tree as `HEAD`, i.e. it does not take any staged changes and only allows
+to fixup the commit message of the specified commit. It will reword the
+specified commit when it is rebased with `--autosquash`.
++
+Also, after fixing the commit using `--fixup`, with or without option
+and rebased with `--autosquash`, the authorship of the original commit
+remains unchanged. See linkgit:git-rebase[1] for details.
--squash=<commit>::
Construct a commit message for use with `rebase --autosquash`.
