[whatwg] charset sniffing algorithm and space characters around the charset name

[Henri Sivonen]

As written, the charset sniffing algorithm doesn't trim space  
characters from around the tentative encoding name. html5lib test  
case expect the space characters to be trimmed.

I suggest trimming space characters (or anything <= 0x20 depending on  
which approach is the right for compat).
