[wwwdocs] Fix quoting in gcc-4.7/porting_to.html

[Josh Stone]

Hi,

I noticed that the porting example for c++11 user-defined literals is
using "smart" double quotes, when code should have straight quotes.
There's also an operator term that should be in the nearby <code> block.

Thanks,
Josh

        * htdocs/gcc-4.7/porting_to.html: Use straight quotes in code
        examples, and expand a <code> wrapper around the operator term.
