[PATCH 0/3] short syntaxes for 'git stash'

[Matthieu Moy <Matthieu.Moy@imag.fr>]

This small patch serie is based on the following commit in pu:

dda1f2a Implement 'git stash save --patch'

It is meant to replace two commits already there:

ea41cfc Make 'git stash -k' a short form for 'git stash save --keep-index'
f300fab DWIM 'git stash save -p' for 'git stash -p'

The first (git stash -k) has the drawback of forcing one to use one
and only one option when the 'save' command is ommited. My approach is
mostly based on the simple hack:

+case "$1" in
+    -*)
+       set "save" "$@"
+       ;;
+esac
+

and accepts an arbitrary number of options.

The second (DWIM git stash save -p) becomes unnecessary afterwards.
