It's a shame that its name is just random gibberish, because that > makes it impossible to set up a gitignore rule for it. I've seen it once or twice, too. It's always st[A-Za-z0-9]{6}, at least on my system.

But I think that: /st[0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z] in your .git/info/excludes (or user-level gitignore) would work if you want, and is probably not too likely to hit false positives (since it lacks an extension). I do feel like I have only started seeing it in the last month or so. I wonder if a new version of binutils changed behavior or something. -Peff
