Summary: Hydrogens

Initial Comment:
I tried the following search.

/usr/local/bin/babel /Users/user/Desktop/outputfile.fs -osmi /Users/
user/Desktop/outputfile.smi -s'C[NH2]'
192 candidates from fingerprint search phase
Bus error

I think the problem is that the original file used to generate the .fs did not
have explicit hydrogens. When I add hydrogens there is no error.

This probably raises a wider issue, when searching using a SMILES/
SMARTS that contain an explicit hydrogen the search will fail silently for
files that do not contain explicit hdrogens. Is this correct? If so should I
add a comment to the user docs that you ought to add hydrogens before
any searching?
