pending issue.

for my emacs, I use below logic for auto-pair. but there is an annoying thing that every time i type"{"then "}" will appear on the next two line,for the format of html file, i should delete these whitespace every time. then i have tried to comment below conditon for html-mode-hook and html-helper-load-hook, but auto-pair still work, so i think it should be in html-helper-mode.el that enable this logic, but i really can't find the corresponding part. now just pending on this issue, i will check these later.
