If you don't want the version to be "~1~", then I guess this is okay.
It wasn't clear from your original message that you don't consider
this form a numbered backup file.

If you are okay with having foo.js~ as a simple backup file name of
foo.js.~HEAD~1~ and foo.js.~3~ as its numbered backup, then I see no
issues here.  I just wonder if that would surprise git users (I don't
use it too much, so I don't know).
