Re: [PATCH v11 20/22] stash: convert `stash--helper.c` into `stash.c`

Paul-Sebastian Ungureanu [off-list ref] writes:

The old shell script `git-stash.sh`  was removed and replaced
entirely by `builtin/stash.c`. In order to do that, `create` and
`push` were adapted to work without `stash.sh`. For example, before
this commit, `git stash create` called `git stash--helper create
--message "$*"`. If it called `git stash--helper create "$@"`, then
some of these changes wouldn't have been necessary.

This commit also removes the word `helper` since now stash is
called directly and not by a shell script.

Seeing the recent trouble in "rebase in C" and how keeping the
scripted version as "git legacy-rebase" helped us postpone the
rewritten version without ripping the whole thing out, I wonder if
we can do the same here.

Also, the remaining two patches should be done _before_ this step, I
would think.  I can understand it if the reason you have those two
after this step is because you found the opportunity for these
improvements after you wrote this step, but in the larger picture
seen by the end users of the "stash in C" and those developers who
follow the evolution of the code, the logical place for this "now we
have everything in C, we retire the scripted version" step to happen
is at the very end.

Thanks.
