5f4a686f8c Simplification and size reduction to the printf logic. Remove the bFlags 
parameter from sqlite3VXPrintf() and sqlite3XPrintf().  Use sqlite3XPrintf()
instead of sqlite3_snprintf() for rendering P4 values in EXPLAIN output.

e807bdba86 Add a new hint bit on the flags parameter of sqlite3BtreeDelete(). The new 
BTREE_IDXDELETE bit indicates that the call is to delete an index entry 
corresponding to a table row that has already been deleted.
