Author: imp Date: Sat Feb 17 06:57:25 2018 New Revision: 329442 URL: https://svnweb.freebsd.org/changeset/base/329442 Log: Implement 'T' field matching. Implement 'T' field matching. This is needed to prevent false positives. However, it's not general enough. It only handles one field and there's a ton of edge cases even with that it likely wouldn't handle. To do it more generally and also eliminate a lot of the hackiness that's in this program now, we'd need to creating directories for lookups ala awk, pearl, python, etc. It appears to be sufficient, though, to get my keyboard loaded on boot.
