[PATCH v3 0/6] rebase -i: add config to abbreviate command-names

[Liam Beguin <liambeguin@gmail.com>]

Add the 'rebase.abbreviateCommands' configuration option to allow
`git rebase -i` to default to the single-letter command-names in
the todo list.

Using single-letter command-names can present two benefits.
First, it makes it easier to change the action since you only need to
replace a single character (i.e.: in vim "r<character>" instead of
"ciw<character>").
Second, using this with a large enough value of 'core.abbrev' enables the
lines of the todo list to remain aligned making the files easier to
read.

Changes from v1 to v2:
 - Improve Documentation and commit message

Changes from v2 to v3:
 - Transform a single patch into a series
 - change option name from 'rebase.abbrevCmd' to 'rebase.abbreviateCommands'
 - abbreviate all commands (not just pick)
 - teach `git rebase -i --autosquash` to recognise single-letter command-names
 - move rebase configuration documentation to Documentation/rebase-config.txt
 - update Documentation to use the preferred naming for the todo list
 - update Documentation and commit messages according to feedback
