9199,\ is lost in post revisions,hailin,anonymous,"\ \add \sub  etc in either title or content is lost in post revisions, and when restore from post revisions. 

It's easy to test, eg, with the following simple post
title: test \
Content: hello \ and \add 
\ is lost in every revision, and when restore from revision.

This creates big problems as many math expressions such as LaTeX 
contains \  Many keywords begin with \  
For example: \add \sub \multiple \left \right 

The root cause is that wp_insert_post stripslahses, assuming slashes are added to the input. This is not the case when we read data from db.  The fix I proposed here identified two such places and fixed this above issue.
