So that it's possible to remove certain refs from the list without
removing the objects that are referenced by other refs.
For example this repository:
* 374e8dd (crap) crap
* 4cbbf7b (test) two
* d025ae0 (HEAD, master) one
When using '--branches --except crap':
* 4cbbf7b (test) two
* d025ae0 (HEAD, master) one
But when using '--branches --not crap' nothing will come out.
