Use HEAD as a default target

[stouset]

I have an alias recommit:

$ git config alias.recommit
commit --amend -CHEAD

It occurred to me that git revise HEAD desugars to essentially the same thing and so my alias is no longer needed. It would be nice if git revise used HEAD as a default target, so staged changes would simply be amended to the current commit with no other arguments.

I came here to suggest the same thing. In the majority of cases, I used git commit -a and forgot about untracked files, so I just need to edit the previous commit. Making HEAD default would make that case easier.
