Subject: [PATCH] Fix test failure with Python 3

When run with Python 3.6, test/testdistgeom.py fails with a SyntaxError
about a malformed character escape.  This arises from a failure to escape
literal backslash characters in single-quoted SMILES strings (several
occurrences).  Python 2 accepts this and does the right things with it,
but Python 3 rejects it.

Fixes #2217
