The -{version} basically maps to a version regex, or to be precise: (\d+(?:\.\d+){1,3}).
Using * tends to grab too much, for example if you bundle jquery*, that will include jquery-ui as well which might mess up the ordering. But using jquery-{version}.js would let you avoid having to update your bundle definition every time you upgrade jquery.
Additional things to note:
{version}only works for the last part of the path–basically the file name–not a directory.- multiple version of jquery in the same folder will all get caught up.
