Log Message:
-----------
Fix two different copy-and-paste-os in CSV log rotation logic; one that led to
a double-pfree crash and another that effectively disabled size-based rotation
for CSV logs. Also suppress a memory leak and make some trivial cosmetic
improvements. Per bug #3901 from Chris Hoover and additional code-reading.
