Hi List,

	I think I've found a little bug in org-export-as-html function in org-
html.el file.
	If you're setting an title with some escape character then the title tag 
in html header is set "as is".

for example if your title is foo\_bar then the title tag will be 
<title>foo\_bar</title> instead of <title>foo_bar</title>

	I tried to do the job in the attached patch.
	Hope this could help.

Pierre
