I do consider it an error.
I have now made an L3fgets that can handle any line ending.
I have uploaded an update http://www.hassings.dk/l3/l3p/l3pmacosx.zip
Please try it on the original problem files.

PS. Here is L3fgets, You can use it in ldglite if you like.
As Paul DiLascia says:
/* If this code works, it was written by Lars C. Hassing. */
/* If not, I don't know who wrote it. */
/* Like fgets, except that 1) any line ending is accepted (\n (unix),
\r\n (DOS/Windows), \r (Mac (OS9)) and 2) Str is ALWAYS zero terminated
(even if no line ending was found) */
char *L3fgets(char *Str, int n, FILE *fp)
{
register int c;
int nextc;
register char *s = Str;
while (--n > 0)
{
if ((c = getc(fp)) == EOF)
break;
if (c == '\032')
continue; /* Skip CTRL+Z */
if (c == '\r' || c == '\n')
{
*s++ = '\n';
/* We got CR or LF, eat next character if LF or CR respectively */
if ((nextc = getc(fp)) == EOF)
break;
if (nextc == c || (nextc != '\r' && nextc != '\n'))
ungetc(nextc, fp); /* CR-CR or LF-LF or ordinary character */
break;
}
*s++ = c;
}
*s = 0;
/* if (ferror(fp)) return NULL; if (s == Str) return NULL; */
if (s == Str)
return NULL;
return Str;
}

| (...) Umm, fgets already does what 2) says above (unless you mean when end of file is reached and the function returns NULL). I'm not actually sure what goes into the string when fgets returns NULL. If no line ending is found (either due to EOF (...) (22 years ago, 11-Dec-02, to lugnet.cad.dev.mac)
