Cleanup unicodeobject.c

Browse source 
* Remove micro-optization:
   (errors == "surrogateescape" || strcmp(errors, "surrogateescape") == 0).
   Only use strcmp()
 * Initialize 'arg' members in unicode_format_arg() to help the compiler to
   diagnose real bugs and also make the code simpler to read
