The current glob `*.pkg.tar.?z` is both less restrictive and more restrictive than makepkg, as it accepts any valid unicode character. To be more exact, it's almost completely orthogonal to the one in makepkg. makepkg only accepts .tar.gz, .tar.bz2, .tar.xz, .tar.lzo, .tar.lrz, and .tar.Z and most of those fail to match against a two-char compression type. dbscripts accepts .pkg.tar.💩z which incidentally is what I think of cherry-picking xz and gz as supported methods. Since this can be anything makepkg.conf accepts, it needs to be able to match all that, unless we decide to perform additional restrictions in which case we should still explicitly list each allowed extension. Using bash extended globbing allows us to do this relatively painlessly. Document the fact that this has *always* been some sort of glob, and update the two cases where this was (not!) being evaluated by bash [[ ... ]], to use a not-elegant-at-all proxy function is_globfile() to evaluate globs *before* testing if they exist.
