Depends on who's reading. If I am used to grasping the 4th line as a whole, it makes sense to me to write it as a unit.

There is always more than one possible solution.

Well... nice question... in my opinion, in terms of code maintenance I prefer a few more code lines because is easier for me, but in terms of clean code, less lines are better. What is the better solution? I think that there isn't a better solution, it depends on the programmer.

This was not written for maximum maintainability.

Reading less is easier than reading more though. :P
