Every %(describe) placeholder in $Format:...$ strings in files with the attribute export-subst is expanded by calling git describe. This can potentially result in a lot of such calls per archive. That's OK for local repositories under control of the user of git archive, but could be a problem for hosted repositories. Expand only a single %(describe) placeholder per archive for now to avoid denial-of-service attacks. We can make this limit configurable later if needed, but let's start out simple.
