7abc54021c Avoid a harmless reference to an uninitialized variable following an 
error in FTS3.  This is not a bug.  The change is to silence a valgrind
warning.

b07028f71c Add assert() statements and eliminate needless variable assignments in order 
to get the clang scan-build utility to report zero problems against the
SQLite core.  Clang's static analysis did find one real problem - but it was
in the command-line shell, not in the SQLite core.

ca892a7252 The build works again with -DSQLITE_OMIT_MERGE_SORT. The merge-sorter now 
avoids spilling to disk (letting the in-memory linked list grow without
bound) if PRAGMA temp_store=3.
