Description:
 def get_editor_query(sql):
 """Get the query part of an editor command."""

    sql = sql.strip()

    # The reason we can't simply do .strip('\e') is that it strips characters,
    # not a substring. So it'll strip "e" in the end of the sql also!
    # Ex: "select * from style\e" -> "select * from styl".
    pattern = re.compile('(^\\\e|\\\e$)')
    while pattern.search(sql):
