commit a6317505ead198c23925c93abbb0926f70e02861

Author: Lukas Fleischer <cgit@cryptocrack.de>

ui-plain.c: Do not access match variable in print_*()

Move all code setting the match variable to walk_tree().

This allows for easily moving this variable into a context structure
without having to pass the context to print_*().
