This is not what we are talking about. This part of the code is OK.

I was complaining about this part:

I marked the places in the original part that were actually TAB
characters by sequences of "<<>>" so you can see what I mean.

[Actually, the comment-end markers "*/" should be aligned by TABs,
too.]
