Re: [PATCH 0/2] Making "git commit" to mean "git commit -a".

...  Rather,
"building your next commit incrementally in the index is the
workflow git is designed to support, but you are not required to
do that _incrementally_.  Until you encounter a complex
situation such as resolving a large conflicting merge, doing
that incrementally does not buy you anything as long as you work
in a clean working tree.

Side note.  I think the above "Until..." is an overstatement,
and maybe the readers of the tutorial can be taught a lot
earlier how the index can help them.  Maybe the following
sequence can be added to an early part of the tutorial sequence?

 $ edit hello.c
 $ make test
 $ git diff
 $ git update-index hello.c; # ok, that is good so far.
 $ edit hello.c; # hack more
 $ make test; # oops, does not work
 $ git diff; # ah, that overeager edit broken what was good
 $ git checkout hello.c; # get the last good one back
