I don't think this one is a good change. git_mkstemp is a library
function, and there are places that indirectly call it (via the gpg
code) that do not die when it fails (and even if all the callers _did_
die, isn't "could not create temporary file ..." a better error message
than "BUG: attempt to snprintf into too-small buffer"?).
