When splitting with -d, the numbering screws up after 89:

with --suffix-length=2 the numbering works correctly, and quits after 99.

This is using the version of split bundled with kubuntu 20.04

It behaves like that on purpose so that there is no limit on the
number of file names to split, and so that normal globbing will
result in the correct order
(so that `cat lat_lon_* > lat_lon_full` works as expected)

Well if there is more data than can be accommodated in 100 files it will error like:

  $ truncate -s 101 file
  $ split -b1 -d --suffix-length=2 file
  split: output file suffixes exhausted

You can specify a larger --suffix-length to have both more
natural looking numbers, and correct globbing order.

thanks,
Pádraig

Fair enough. I didn't see anything about that in the help or man page,
perhaps a note should be added there?
