• runtime/JSGlobalObjectFunctions.cpp:

(JSC::globalFuncUnescape): Restructured to handle
the %uHHHH case to output the resulting character
and continue so that a failure in finding 4 hex
digits will fall through and output the '%'.
Due to style check, changed the temporary
character variable to a more descriptive name.
