Sorry but GLOB doesn't use an index either if LIKE/GLOB has been 
overloaded.  This is consistent with the docs and the output of Explain 
query plan for both variants when an extension is active and overloads 
LIKE/GLOB.

Things can be different with a custom built of SQLite, where native 
LIKE/GLOB itself has been modified.  With custom code, all bets are off.
