4b0229ae1f Enhance the ".once" and ".output" commands in the CLI so that if the 
filename argument begins with "|" the name becomes the concatenation
of all subsequent arguments.  Hence, commands like ".once | open -f" become
possible without the need for quotes.

70bd2124ed Change the RETURNING algorithm so that outputs accumulate in an ephemeral 
table until all modifications have been completed, and only then do results
start being returned.  This should help prevent problems with interleaved
sqlite3_step() calls on two separate DML statements.  It also seems to be
closer to how PostgreSQL works, which might prevent compatibility problems.

2aa41c82da Modify the SQLITE_DBCONFIG_ENABLE_TRIGGER setting so that it only disables 
main-schema triggers and allows TEMP trigger to continue operating.  This is
safe, since only the application (not an attacker) can add TEMP triggers.
It will also all us to disengage SQLITE_DBCONFIG_ENABLE_TRIGGER on Fossil
databases since Fossil has no main-schema triggers but does use TEMP triggers.
