Re: How to implement the "amend!" commit ?

This is the only option that is backwards

new syntax as `--fixup=amend::/<text>`.

Do you mean both "--fixup=:/<text>" and "--fixup=amend::/<text>"
work and do the same thing?  If so, that is good.

Note that we intend to allow
accept any prefix of "amend" and "reword" so --fixup=a:<commit> would
work.

"a" and "r" may happen to be unique but we would not want to be
limited to these two forever---future developers are allowed to
invent other clever variants.  So let's say "accept unique prefix as
abbreviation for these operating mode words like 'amend' and 'reword'"
