Actually, it does not matter, as once __git_list_all_commands is
run, its result is kept in a variable.

So Peff's

  if test -z "$FAKE_COMMAND_LIST"; then
          __git_cmdlist() {
                  git help -a | egrep '^  [a-zA-Z0-9]'
          }
  else
          __git_cmdlist() {
                  printf '%s' "$FAKE_COMMAND_LIST"
          }
  fi

would be just as simple if not simpler, does the same thing, and is
sufficient, I think.

The t9902 test is only interested in making sure that the completion
works, and we do not want "git help -a" that omits a subcommand from
its output that is not built in your particular environment to get
in the way, which will not be an issue with this approach.
