Not really - it only changes the return code - the text is left as is...
negate did work in the last stable release... The error you are seeing was

[sghosh at calcutta plugins]$ ./negate ./check_fping -H jersey ; echo $?
FPING CRITICAL - jersey (loss=100% )|loss=100%;;;0;100
0
[sghosh at calcutta plugins]$ ./check_fping -H jersey ; echo $?
FPING CRITICAL - jersey (loss=100% )|loss=100%;;;0;100
