Summary: wrong mol2 -> SMILES conversion

Initial Comment:
there is a problem with indicating Z/E isomers in SMILES generated from mol2 
files.

Eg. for 1,2-dichloroethane. For structures saved in mol files, smiles (smi or 
can) are generated correctly:
>babel Z.mol -o can
Cl/C=C\Cl       Z
1 molecule converted
32 audit log messages

>babel E.mol -o can
Cl/C=C/Cl       E
1 molecule converted
32 audit log messages

while for files saved in mol2 format, we dont get the E/Z isomerism:

>babel Z.mol2 -o can
ClC=CCl Z
1 molecule converted
32 audit log messages

>babel E.mol2 -o can
ClC=CCl E
1 molecule converted
32 audit log messages

Converting mol2 back to mol fixes the problem.

greetings,
F
