When running "git show-branch" without any parameter in a repository that
has showbranch.default defined, we used to rely on the fact that our
handcrafted option parsing loop never looked at av[0].
The array of default strings had the first real command line argument in
default_arg[0], but the option parser wanted to look at the array starting
at av[1], so we assigned the address of -1th element to av to force the
loop start working from default_arg[0].
This no longer worked since 5734365 (show-branch: migrate to parse-options
API, 2009-05-21), as parse_options_start() saved the incoming &av[0] in
its ctx->out and later in parse_options_end() it did memmove to ctx->out
(with ctx->cpidx == 0), overwriting the memory before default_arg[] array.
I am not sure if this is a bug in parse_options(), or a bug in the caller,
and tonight I do not have enough concentration to figure out which. In
any case, this patch works the issue around.
