lineoffset slower than "repeat for each line j" ?

filter is even slower than lineoffset : 260 ms
Besides I can't use filter in my case, since I need to replace values in the 1st
and 2nd items of the found lines, and filter just picks the line and separates it
from the context...

yep, actually I guess that lineoffset and filter, once compiled, use rather
complex routines, while "repeat for each line" remains much closer to raw
and efficient C code...
