magnum, Fred -

To see how much room for improvement there still is in ldr_split_line(),
I've just tried dropping its portions irrelevant to this file with only
raw-md5's in it.  Patch attached (of course, not to be committed).

My previous best result was:

real    0m48.370s
user    3m0.279s
sys     0m19.045s

With this patch, it improved to:

real    0m45.481s
user    2m57.928s
sys     0m18.315s

which is roughly 24 seconds loading and 21.5 seconds cracking.

Alexander
