I think GitHub does similar. But I'm worried > about the general masses who might be using our software and expect > ref names thus far to be as long as PATH_MAX on their system.

I don't recall ever seeing any complaints about that, though I suppose it's not out of the realm of possibility for somebody with a multi-byte encoding to hit with a real name (it's configurable, so I'm not sure if Enterprise customers in Asia might ever bump it). I do think something like 1024 would be well into "you're insane if you really want to name your branch this" territory. -Peff
