Commit3eb1bc6

committed

Check explicitly for valid input strings for both TRUE and FALSE.

Allow true/false, yes/no, 1/0. Throw elog warning if anything else.Allow shorter strings, so "t", "tr", "tru" and "true" match "true".Old behavior accepted anything starting with "t" as TRUE, everything else as FALSE.
