A typo

V501 There are identical sub-expressions ‘cmdline_state != GRUB_PARSER_STATE_QUOTE’ to the left and to the right of the ‘&&’ operator. completion.c 502

typedef enum
{
  GRUB_PARSER_STATE_TEXT = 1,
  GRUB_PARSER_STATE_ESC,
  GRUB_PARSER_STATE_QUOTE,
  GRUB_PARSER_STATE_DQUOTE,
  ....
} grub_parser_state_t;

char * grub_normal_do_completion (....)
{
  ....
  if (*escstr == ' ' 
      && cmdline_state != GRUB_PARSER_STATE_QUOTE
      && cmdline_state != GRUB_PARSER_STATE_QUOTE)  
        *(newstr++) = '\\';
  ....
}

Typos in similarly looking names of constants are quite a common issue. In the example above, the programmer must have intended to compare the value of cmdline_state with the GRUB_PARSER_STATE_DQUOTE constant instead of comparing it with GRUB_PARSER_STATE_QUOTE one more time.
