Martin Caslavsky 675bf57006 fix: allow escape value to be an empty string ...

Fixed issue where the :paramref:`.ColumnOperators.like.escape` and similar
parameters did not allow an empty string as an argument that would be
passed through as the "escape" character; this is a supported syntax by
PostgreSQL.  Pull requset courtesy Martin Caslavsky.
