Comment #1 on issue 778 by pekka.klarck: Incorrect presentation of
arguments for method ' :For' using multiple variables

First of all, this issue is Invalid here and should be submitted to RIDE's
tracker instead:

The underlying problem in your case is that RIDE fully loses source
formatting when it gets the data from Robot's internal modules. This is a
known limitation we aren't planning to do anything in the foreseeable
future.
In this particular case RIDE could format the for loop better, though. It
could probably show one set of variables in one row, just like in your
original source, always when there are more than one loop variables.
