1. bc: yyparse() loop regression …

   * A previous commit replaced a goto into yyparse() with a call to yyparse() but this introduced an infinite loop for a file with a syntax error
   * yy_err_recover() returns bool; returning 1 instead of calling yyparse() again allows yyparse() to itself return and break out of "yyloop"
   * The pattern of return(1) from yy_err_recover() was already established; this patch just makes it more consistent
   * test1: echo '1++' > A.bc && perl bc -y A.bc
   * test2: echo '~' > B.bc && perl  bc -y B.bc
