ISSUE:       6046
TITLE:       execute statement ignores the text of the SQL-query after a comment of the form "-"
DESCRIPTION:
    We concatenate query from several elements and use <CR> delimiter only to split this query into lines.
    Also, we put single-line comment in SEPARATE line between 'select' and column/value that is obtained from DB.
    Final query will lokk like this (lines are separated only by SINGLE delimiter, ascii_char(13), NO <CR> here!):
    ===
        select
        -- comment N1
        'foo' as msg'
        from
        -- comment N2
        rdb$database
    ===
    This query should NOT raise any exception and must produce normal output (string 'foo').
    Thanks to hvlad for suggestions.
