The commandline don't echo document or comment of the symbol when let g:vista_echo_cursor_strategy = 'echo'

[JohanChane]

for example

        xml_attribute<Ch> *m_next_attribute;        // Pointer to next sibling of attribute, or 0 if none; only valid if parent is non-zero

When the cursor on the m_next_attribute yield in vista, the commandline echo Press ENTER or type command to continue, for the message is too long. Though I can set cmdheight=2 to sovle this, I want that the commandline don't echo document or comment of the symbol since document or comment is always too long for commandline.
