Toen wij LuKreme kietelden, kwam er dit uit:

Where the $ is a newline. 

This is the same:

   * B ?? ^VAR

(maybe unless SHELLMETAS contains V, A or R?)


But ^^ is not the same as $$.


Example-1:

  * var ?? $^^ 

looks for a newline at the end of $var.


Example-2:

  * var ?? ($)($)

looks for two newlines, but since both start and end of 
buffer are putative newlines, a newline at start or end of 
$var will also match. So ($)($) is short for (^^$|($)($)|$^^).

Maybe that the ($)($) there could also be written as $$, 
but $$ also means process-id, so it is more future-proof 
to write it as ($)($).
