#9199: \ is lost in post revisions
 Reporter:  hailin        |       Owner:  anonymous
     Type:  defect (bug)  |      Status:  new      
 Priority:  high          |   Milestone:  2.7.2    
Component:  General       |     Version:           
 Severity:  normal        |    Keywords:           
 \ \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.
