* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): It seems
* tests/indexObj.test: there are extensions that rely on the prior * doc/GetIndex.3: behavior that the empty string cannot succeed as a unique prefix matcher, so I'm restoring Donal Fellow's solution. Added mention of this detail to the documentation. [Bug 1464039]
