The subject line needs to be updated.

Aliases implemented this way don't work the same way as "normal"
aliases do:

  $ # which aliases do I have?
  $ ./bin-wrappers/git config --get-regexp "alias\..*"
  $ # no aliases at all
  $ # does completion work?
  $ ./bin-wrappers/git co ma<TAB>
  mailmap.c      mailmap.h      mailmap.o      match-trees.c  match-trees.o
  $ # no refs completion
  $ # let's see a real alias
  $ git config alias.co checkout
  $ ./bin-wrappers/git config --get-regexp "alias\..*"
  alias.co checkout
  $ ./bin-wrappers/git co ma<TAB>
  maint    master
  $ # as expected


Best,
