With the failing setup and
(setq vc-command-messages t)

I see the following in the *Messages* buffer and it seems OK to me

,----  *Messages* 
| Running git update-index --refresh . in background... done
| Running git diff-index --relative -z -M HEAD -- . in background... done
| Running git ls-files -z -o --directory --no-empty-directory --exclude-standard -- . in background... done
| Running git stash show -p stash@{0} . in background... done
`----

But in the *vc-git-stash* buffer I see the following message

,----  *vc-git-stash* 
| '-p stash@0' is not a stash
`----

Not the absence of `{' `}' in the error report. I hope that provides
some clue on what the underlying git sees.


With my "works for me" changes, I see the following

,---- *Messages*

Let me know if you need more information.

FWIW, git is also from cygwin installation.
