'Repeat all' should work with a single song (from a filter or not).

Currently if you have repeat all selected it will not replay a single song after the end. This is probably a bug (it's been there since forever). It doesn't appear to matter if the song was filtered or is a single (although the only single song GUI views that are not the result of name filters i've seen in a while are from the 'recently added' playlist, so maybe that is automatically filtered).
