case-sensitive ignore strings

[Matt McGrievy]

I'm monitoring a machine which is unfortunately named "panic" and I 
can't seem to get the LOG settings right to flag "PANIC", but not 
"panic" for that host.  Here's the host-specific section in 
hobbit-clients.cfg:

HOST=panic,panic.example.com
         LOG %.* %(?-i)PANIC IGNORE=%panic
         LOG %.* %(FATAL|ECC) COLOR=red

and here's the default section (for all other machines):

DEFAULT
	LOG %.* %(FATAL|PANIC|ECC) COLOR=red

Any ideas why "panic" is still matching?

Thanks,
Matt
