SQL allows comments like:
select name -- department name
However, sqlline doesn't handle this correctly because
it doesn't strip the comment and it converts the
newline into a space, so what gets sent to the JDBC
"select name -- department name from sales.depts"
which a typical JDBC driver will see as just "select
name" after stripping off the comment.
There are other cases where converting newlines into
spaces causes well-formed SQL to turn into bad SQL.
For example, the SQL standard allows multi-line string
select "My Big Fat "
But the standard requires the newline in between the
So the best fix for both problems (and possibly others
not encountered yet) would be to preserve the newlines.
