Actually, I was at fault giving up on Matthieu's patch without studying it
after seeing the phrase "this series replaces", when the two topics the
series tried to replace were already in 'next'.
It turns out that the rework was simple enough, so I did it myself. Among
his 3 patch series, an equivalent to the first one ("save -keep" can be
written as "save -k" for brevity) were already in, and the second one
(default to "save" if we see any option before command word) was unsafe
without the third one (reject unknown option to "save"), so it ended up as
a single patch that is a combination of the latter two patches.
This applies on top of tr/reset-checkout-patch branch, 14c674e (Make test
case number unique, 2009-08-27).

Subject: [PATCH] stash: simplify defaulting to "save" and reject unknown options
With the earlier DWIM patches, certain combination of options defaulted
to the "save" command correctly while certain equally valid combination
did not. For example, "git stash -k" were Ok but "git stash -q -k" did
not work.
This makes the logic of defaulting to "save" much simpler. If the first
argument begins with a '-', it is clear that there is no command word,
and we default to "save" subcommand.
This also teaches "git stash save" to reject an unknown option. This is
to keep a mistyped "git stash save --quite" from creating a stash with a
message "--quite", and this safety is more important with the new logic
to default to "save" with any option-looking argument without an explicit
comand word.
[jc: this is based on Matthieu's 3-patch series, and he takes all the
credit; if I have introduced bugs while reworking they are mine]
