Comment (by knarf):

 I didn't find the string "PREVIOUS_TIME_LEVEL" anywhere in my source
 checkout (which is larger than the ET), other than in this section of the
 code. The question here isn't about pre-MoL code. That is fine. The code
 in question looks for a possibility to declare which variable the previous
 timelevel of another variable is by table entry and name/index lookup, as
 opposed to the now used *_p naming scheme. Up to yesterday I didn't even
 know this possibility existed once. :)
