Subject: changed [l2s] argument incompatibly: the argument is now the
 delimiter (analogous to [s2l]) instead of the default list to be converted.
 while this is an incompatible change, i noticed that the argument handling
 was broken anyhow (produced rather random results, even in the help-file!)
 and since nobody noticed i guess the arguments are not used anyhow....
