This is equivalent to a diff from 1a0d7d3d to f03fbf37

| 18:23 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: d01cedaa user: drh tags: trunk) | |
| 18:21 | Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e) | |
| 17:19 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: 0deac873 user: drh tags: tkt-55746f9e) | |
| 15:46 | Add the SQLITE_IOCAP_IMMUTABLE bit as a possible return value from the xDeviceCharacteristics method in the VFS. Add the "nolock" and "immutable" query parameters to URI filenames. (check-in: 1a0d7d3d user: drh tags: trunk) | |
| 15:32 | Fix nolock and immutable so that they work even if READONLY is requested. (Closed-Leaf check-in: e193aced user: drh tags: win32-none) | |

| 21:37 | Update the template VSIX package file as well. (check-in: 99d96765 user: mistachkin tags: trunk) | |
