Tidy has to use a rule of thumb to detect missing trailing
quote marks and missing close tag symbols (">"). This works
by giving bad marks to a number of features and reaching a
conclusion once the aggregate score exceeds some limit.

It is no good tweaking these rules which are there for the
common case. Instead, it will be necessary to switch
off the quotemark rule and preserve the line breaks as per
the authors original intentions.

It is a shame that the plugin relies in the line breaks
as this prevents this markup from being reflowed. For
JavaScript literals, Tidy know's how to escape any newlines
it inserts so that these don't effect the script. What you
have is the reverse - the line breaks are significant and
need to be preserved.

I will look into this.

Perhaps the solution is to add a new config option to 
declare particular attributes as behaving like PRE content.
