CLEANUP: The exact same test was performed twice.

Version: 1.29.4 [2014-01-26]
o Now commandArgs(asValues=TRUE) returns no-named arguments as a
  list element with the argument as the value and with a "" name.
  For instance, in the past one would get list(R=NA, a="1", noname=NA)
  whereas now one gets list("R", a="1", "noname").
o BUG FIX: Now attachLocally() no longer tries to attach elements with
  an empty name, e.g. list(a=1, 2).  Previously it gave an error.
  Added a package system test for attachLocally().
