> Behavior changed to match PostgreSQL on trunk.
A pedantic micro-optimization:
```
if( escape==pInfo->matchAll || escape==pInfo->matchOne ){
memcpy(&backupInfo, pInfo, sizeof(backupInfo));
pInfo = &backupInfo;
if( escape==pInfo->matchAll ) pInfo->matchAll = 0;
if( escape==pInfo->matchOne ) pInfo->matchOne = 0;
}
```
*Presumably* `matchAll` and `matchOne` may never be the same character, in which case those adjacent inner `if`'s could be changed to an `if/else if`.
