Subject: regex.c and RE_FRUGAL

Hello!

This bug report is not quite for emacs, but for its regex library.

It features RE_FRUGAL flag (very useful), but it does not seem to work.

I have tried this rather simple program and it prints 0-12 instead of expected 0-6.

Please advice.

#include "config.h"
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include "regex.h"
int main()
{
   const char *rexp="<.*?>";
   static struct re_pattern_buffer rexp_c;
   static struct re_registers regs;
   re_syntax_options = RE_FRUGAL;
   re_compile_pattern(rexp,strlen(rexp),&rexp_c);
   if(re_search(&rexp_c,"<html><head>",12,0,12,&regs)==-1) {
      printf("search failed\n");
      return 1;
   }
   printf("%d-%d\n",regs.start[0],regs.end[0]);
   return 0;
}
