Fix typo in help information for an FTS5 script. check-in: 777ae800 user: mistachkin tags: trunk
20:25
The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk.
