NRPE check_proc -C name with spaces

[WolfgangArndt]

hello all,
I can't get along with check_proc -C, if there are spaces in the name,
for example, process name is 'AirPort Base'.
all variants of writing gives 0 processes with command name 'AirPort Base' back, thats definitly wrong!
check_proc -C "AirPort Base"
check_proc -C 'AirPort Base'

Does anybody has a good idear ?

thanks wolfgang
