Ensure that the cited expression is not a function call or an assignment to reduce the chance of false positives. Slightly modify the warning message to indicate another source of false positves.

2016-01-12coccinelle: tests: unsigned value cannot be lesser than zeroAndrzej Hajda
Unsigned expressions cannot be lesser than zero. Presence of comparisons 'unsigned (<|<=|>|>=) 0' often indicates a bug, usually wrong type of variable. The patch beside finding such comparisons tries to eliminate false positives, mainly by bypassing range checks. gcc can detect such comparisons also using -Wtype-limits switch, but it warns also in correct cases, making too much noise.
