Numbering lines

[hh]

What's interesting with that is once again a comparison LC 6 against LC 9.

I tested with 10000 lines of text (King James bible, Genesis up to 5|16) and
*non-wrapping fields*, separator tab:

LC 9.0.1  needs in average 370 ms for numbering, 330 ms for denumbering,
LC 6.7.11 needs in average 170 ms for numbering, 140 ms for denumbering.

Without field update, only the text handling, this reduces to:

LC 9.0.1  needs in average 75 ms for numbering, 75 ms for denumbering,
LC 6.7.11 needs in average 45 ms for numbering, 18 ms for denumbering.

So, LC 9 has become pretty fast, but reaches, at least with arrays and field
updates, not yet the speed of LC 6 (hardware used: Mac mini, 2.5 GHz).
