"apply" does not touch the HEAD but it can touch the index; when it
operates with the "--cached" or the "--index" option, it should not
be considered as a working-tree-only command.

"am" is about recording what is in the patch as a commit.

I do not particularly think it is so bad.

How would we handle the case where the user modifies paths outside
the sparse specification and makes a commit out of the result,
without using "am"?  We should be consistent with that use case, i.e.

    $ edit path/outside/sparse/specification
    $ git add path/outside/sparse/specification
    $ git commit

Do we require some "Yes, I am aware that I need to widen my sparse
specification to do this, because I am now stepping out of it, and I
understand that my sparse specification becomes wider after doing
this operation" confirmation with "add" or "commit"?  If not, then I
think "am" should silently widen just like these commands.  If they
do, then "am" should also require such an option.  Perhaps call it
"--widen-sparse" or whatever.

By the way, I like the term "sparse specification" very much, as
we should worry about non-cone mode as well.  Please use it
consistently in this document after getting a concensus that it
is a good phrase to use from others---I saw some other words
used after "sparse" elsewhere in this patch.

I suspect that leaving it tree-wide would allow scripters come up
with Porcelains that restricts to the sparse specification more
easily.

Thanks.
