Vl-skip-through-endtask

Barbaric fault tolerance routine. Find endtask so we can try to resume parsing after a problematic function.

Signature

(vl-skip-through-endtask &key (tokstream 'tokstream) 
                         (config 'config)) 
 
  → 
(mv errmsg? value new-tokstream)

Arguments

config — Guard (vl-loadconfig-p config).
