I have written the code to speed up the new parser.
The current code for `corfile_puts' uses two loops, one for `strlen'
and one for `strcat'. The new code uses only a loop for the string.
Besides, it preserves the NUL chars to the end (like `strcat'),
necessary for the new parser. Here is the code:

void corfile_puts(char *s, CORFIL *f)
{
    char *c;
    int n;
    /* skip and count the NUL chars to the end */
    for (n=0; f->p > 0 && f->body[f->p-1] == '\0'; n++, f->p--);
    /* append the string */
    for (c = s; *c != '\0'; c++) {
      f->body[f->p++] = *c;
      if (f->p >= f->len)
        f->body = (char*) realloc(f->body, f->len+=100);
    }
    if (n > 0) {
      /* put the extra NUL chars to the end */
      while(--n >= 0) {
        f->body[f->p++] = '\0';
        if (f->p >= f->len)
          f->body = (char*) realloc(f->body, f->len+=100);
      }
    }
    f->body[f->p] = '\0';
}

It passes the extensive tests (also faster).

Is it good for you?
