[PATCH v2 0/9] rebase -i: add config to abbreviate command names

Hi everyone,

This series will add the 'rebase.abbreviateCommands' configuration option to allow `git rebase -i` to default to the single-letter command names when generating 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 in V2:
- Refactor and rename 'transform_todo_ids'
- Replace SHA-1 by OID in rebase--helper.c
- Update todo list related functions to take a generic 'flags' parameter
- Rename 'add_exec_commands' function to 'sequencer_add_exec_commands'
- Rename 'add-exec' option to 'add-exec-commands'
- Use 'strbur_read_file' instead of rewriting it
- Make 'command_to_char' return 'comment_char_line' if no single-letter
  command name is defined
- Combine both tests into a single test case
- Update commit messages

Changes in V2:
- Rename 'transform_todo_insn' to 'transform_todos'
- Fix flag name TODO_LIST_SHORTE{D,N}_IDS
