Overview
| Comment: | Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. |

| 16:04 | Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer).
