stash: fix show referencing stash index
In the conversion of 'stash show' to C in dc7bd382b1 ("stash: convert
show to builtin", 2019-02-25), 'git stash show <n>', where n is the
index of a stash got broken, if n is not a file or a valid revision by
itself.
'stash show' accepts any flag 'git diff' accepts for changing the
output format. Internally we use 'setup_revisions()' to parse these
command line flags. Currently we pass the whole argv through to
'setup_revisions()', which includes the stash index.
As the stash index is not a valid revision or a file in the working
tree in most cases however, this 'setup_revisions()' call (and thus
the whole command) ends up failing if we use this form of 'git stash
show'.
Instead of passing the whole argv to 'setup_revisions()', only pass
the flags (and the command name) through, while excluding the stash
reference. The stash reference is parsed (and validated) in
'get_stash_info()' already.
This separate parsing also means that we currently do produce the
correct output if the command succeeds.
