Is it better for "rev-parse" to be more careful, and to behave more like
the rest of git? Or is better to be historically compatible?
One thing to note is that "git rev-parse HEAD" is slightly broken there
already. Because "git rev-parse $some_branch" may do very different
things than what the caller expects if $some_branch does not exist (but
there is a file with the same name). So maybe we are doing a favor by
calling out the problem; if they want a rev, they should be using
"--verify" (or "--").
I tend to agree with the reasoning in the last sentence. Let's cook
it for a while and see what happens.
Thanks.
