This bug was disovered by someone on IRC when he tried to 'git stash branch <branch> <stash>'
while <branch> already existed. In that case the stash is dropped even though it isn't
applied on any branch, so the stash is effectively lost. I think that shouldn't happen,
so here is a test.

This series fixes another (sorry!) regression I introduced with my detached-stash series.
I have included Tomas' test, so that my tweak to the test script applies cleanly.

Tomas Carnecky reported a regression in the behaviour
of git stash branch, when the branch creation fails.
This patch fixes that regression by restoring the
pre-condition for dropping that previously existed.
This patch assumes Tomas Carnecky's patch has already been applied.

This line was missing from my original patch, sorry about that:

Junio,
Let me know if you want me to re-roll this series with Tomas'
sign-off. I can also add my simplification of the Brian's fix and
another fix I have made to have git stash save/create fail early in
case the index contains merge conflicts.
jon.
