Question

When one commits using commit -a a default editor pops up, prefilled with the contents of the git status command (but with all the lines preceeded by a pound sign).

Is it possible to have the output of git diff prefill the editor instead of the contents of git status ?

Answer 1

Yes, it is made possible by the use of the --verbose flag; your full command becomes then git commit -a --verbose or, more concise, git commit -av.
