sql.py: map_expr(): Replacing without quotes: Don't match unquoted name where it's preceded or followed by '.', because this could be a '.' embedded in a punctuation-containing column name, such as those frequently used by column-based import. Note that because database-internal names currently do not contain punctuation, this situation only occurs when a database-internal expression (such as a check constraint condition) is replaced in two steps, and the first step introduces punctuation-containing column names into the expression.
