Indeed.  My only concern is whether these directories have been created by the R DMG installer and have *never* been used by any other program to put some Tcl/Tk related file (or not just those, especially in the ‘man’ directories!).  Hence my desire to remove the files in the list, so I can ascertain post-hoc whether the directories are empty or not (and thus remove them).
