Unless there's a misunderstanding somewhere, this is not an exception  
at all: you MIGHT escape the quotes in the title if you want, it's  
only that you don't really have to. The characters you MIGHT escape  
are the same everywhere, the characters you MUST escape depends on  
the context you're in.

At least, that's the theory. If you really wanted to show a backward  
compatibility problem, you could have given this:

     [alt text](/url/ "Title with \" quotes \" inside")

In this case, using either Markdown.pl or PHP Markdown, the  
backslashes are taken literally and show up in the title attribute.  
I'd tend to believe this is a bug.

A side effect of this is that there's no way to include the string ")  
within a title attribute inside an inline-style link, nor can you add  
some space between the quote and the closing parenthesis to avoid the  
problem.
