My 0.02€: ISTM that the number of columns should stay the same whether it 
is skipped or not, so the "file_no" should be kept. Maybe to keep it a 
number would make sense (-1) or just a sign (-) which means "no value" 
with gnuplot for instance. Or "skipped".
Basically I would be fine with that, but as I do not use the log file 
feature I'm not sure that my opinion should count.
Note that there are also potential issues with the aggregate logging and 
the sampling stuff.
