This option makes it convenient to construct commit messages for use
with 'rebase --autosquash'. The resulting commit message will be
"fixup! ..." where "..." is the subject line of the specified commit
message.
Example usage:
$ git commit --fixup HEAD~2

Like '-C', but with '-c' the editor is invoked, so that
the user can further edit the commit message.
+--fixup=<commit>::
+ Construct a commit message for use with `rebase --autosquash`.
+ The commit message will be the subject line from the specified

--reset-author::
When used with -C/-c/--amend options, declare that the
