Empty string returned (Regular Expression has PREG_BACKTRACK_LIMIT_ERROR) about minify HOT 4 CLOSED

Thanks for catching this. I'm all for optimizing (or removing) regexs if 
possible. 
In this case your fix won't have the same functionality (basically a trim of 
each 
line). Can you try replacing with these lines instead?

$html = preg_replace('/^\\s*/m', '', $html);
$html = preg_replace('/\\s*$/m', '', $html);

Fixed in R160. ecroyd, can you verify this worked? I combined the patterns 
suggested 
above:

$html = preg_replace('/^\\s+|\\s+$/m', '', $html);

Both your latest solution (comment 2) and your earlier solution (comment 1) fix 
my
problem.

Thank you very much for providing such a great tool.
