[whatwg] Find a number with "." as the input

[Henri Sivonen]

The definition of "find a number" ( http://whatwg.org/specs/web-apps/ 
current-work/#find-a ) may cause a string containing a single U+002E  
FULL STOP to be fed to the algorithm entitled "rules for parsing  
floating point number values" ( http://whatwg.org/specs/web-apps/ 
current-work/#rules1 ). The definition for "find a number" claims  
that this step can never fail, but step 9 in "rules for parsing  
floating point number values" returns an error in this case.
