Look at the "FILENAME GENERATION" section of zshexpn(1).

	% history -m "^" 1                  # Shows everything
	% history -m "^nosuchstring" 1      # Also shows everything

With EXTENDED_GLOB set, "^" matches anything except the empty string,
and "^nosuchstring" matches anything except the string "nosuchstring".

	% history -m "$" 1                  # Shows nothing

The character "$" is not special in patterns, so this only matches
the string "$".
