#652 smarts.findall(mol) doesn't work after AddHydrogens()

[Pascal Muller]

Some smarts patterns are no more recognised after calling AddHydrogens(), like acetal, aminal and thioacetal smarts found on http://ligand-expo.rcsb.org/dictionaries/fp_patterns.txt.
Other smarts, like heminal or hemiacetal, are matched before and after calling AddHydrogens().
All smarts work with obgrep.
See attached file for used smarts.
