mod_bookmarks: Suppress error publishing empty legacy bookmarks w/ no PEP node It appears that when: 1) The user has no bookmarks 2 node in PEP 2) The client publishes an empty bookmark set to a legacy bookmarks location 3) mod_bookmarks will attempt to purge items from the non-existent node and log an error about the failure (item-not-found). This new code will suppress an item-not-found error from the purge operation in the empty-bookmarks case, and adds a log message for any other error (this is helpful because the existing log message confusingly says it was an error *publishing* to the node, which isn't always accurate).

local data = {}
local getinfo = debug.getinfo;
local function linehook(ev, li)

		local file = S.source:sub(2);
		local lines = data[file];
		if not lines then
			lines = {};
			data[file] = lines;
			for line in io.lines(file) do
				lines[#lines+1] = line;
			end
		end
		io.stderr:write(ev, " ", file, " ", li, " ", lines[li], "\n");
