[PATCH v3 2/6] rebase -i: add abbreviate_commands function

[Liam Beguin <liambeguin@gmail.com>]

Once the rest of the processing is done, the `abbreviate_commands`
function is called. If the 'rebase.abbreviateCommands' option is set to
true, the function will replace each command-name by its abbreviated
form.
