The "do we have --all?" test added by that old commit is not quite
satisfying in the first place. E.g. we do not check if there is a
double-dash before it. This change also relies on an ancient design
mistake of allowing non-dashed options before a dashed one, adding
more to dissatisfaction by making a future change to correct the
design mistake harder.
I think in the longer term we should consider changing "git
rev-parse --all" to include HEAD in the concept of "all refs"
instead. But in the meantime, this patch is not making things
drastically wrong, so let's take it as is.
Thanks.
