Sadly, the combination of "-o" and "-i" is broken in grep 2.5.1 in this sort of 
way: whether it finds a match depends on the combination of cases used in the 
pattern and in the text being searched.  Various Linux distributions provide 
patched versions of grep that may work better or differently, but basically 
that combination of modes is still broken.

I don't have any explanation for why it works in the console but not in the 
cron job, unless the cron job is picking up a different "grep" program because 
its active PATH is different.
