tglsfdc · tglsfdc · commit 1630f5b92a3a · 2016-04-10T23:52:34.000-04:00
Coverity complained about an apparent missing "break" in a switch added by bb14050. The human-readable comments are pretty clear that this is intentional, but add a standard /* FALL THRU */ comment to make it clear to tools too.
