[PATCH 2/2] fix a bug that use option '-k key-string' cannot search out all matched logs



Hello Steve, 

Use option '-k key-string' cannot search out the log which contains the given key-string and message type is CONFIG_CHANGE.

For example:
echo 'node=RHEL5.2GA type=CONFIG_CHANGE msg=audit(1217404709.683:23182): auid=0 subj=root:system_r:auditctl_t:s0-s0:c0.c1023 op=remove rule key="haha" list=4 res=1' | ausearch -k haha
The output is: <no matches>
