Current git rev-parse behaviour makes --flags hard to use if the remaining
arguments to git rev-parse contain an option that would otherwise be interpreted
as an option by git rev-parse itself.
So, for example:
$> git rev-parse --flags -q -X
-X
Normally one might expect to use -- to prevent -q being interpreted:
$> git rev-parse --flags -- -q -X
-q -X
But we can't really use -- in this way, because commands that use
git rev-parse might reasonably expect:
$> git rev-parse --flags -Y -- -q -X
-Y
That is, -Y to be regarded as a flag but everything after -- to be uninterpreted.
This proposed change modifies git rev-parse so that git rev-parse stops
interpreting flag arguments as options to git rev-parse once --flags is
interpreted. We also exit early once -- is found.
Tests will follow in subsequent iterations of this patch, if the consensus
is that the approach is correct.
