eaf4f523a5 Remove a condition that is always in the logic that handles reading 
default values for columns.

c73d0d9dec Fix harmless compiler warnings in FTS4. This involved corrupting 
Martin Porter's beautifully written and elegant stemmer code, making it
a little less beautiful and a little less elegant.  Today is a sad
day.  But the warnings from GCC grow increasingly verbose and irksome
with each new release and so something had to be done.

849a9d92ba Fix the ".echo on" dot-command of the shell so that it echos comments in 
addition to SQL statements and dot-commands.  Add the --explain option
to speedtest1 so that the output can be piped into the command-line shell
to show nicely-formated VDBE code for the entire test.

1d8b85bed1 Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests.
