I had suggested two possibilities, not just mixedsort. The other was mixsort:

*> mixsort("a.b.c")
*

[1] "a.b.c"

*> print(mixsort("a"))
*

[1] "a"

*> print(mixsort("a."))
*

[1] "a."

*> print(mixsort("a.b"))
*

[1] "a.b"

*> print(mixsort("a.b."))
*

[1] "a.b."

*> print(mixsort("a.b.c"))
*

[1] "a.b.c"

*> print(mixsort("a.b.c."))
*

[1] "a.b.c."
