This snipset from the 2.11 main.c is very likely the culprit. The
'S_ISFIFO (stats->stat.st_mode)' causes stdin to be skipped if it is a
pipe.
if ((directories == SKIP_DIRECTORIES && S_ISDIR (stats->stat.st_mode))
|| (devices == SKIP_DEVICES && (S_ISCHR (stats->stat.st_mode)
|| S_ISBLK (stats->stat.st_mode)
|| S_ISSOCK (stats->stat.st_mode)
|| S_ISFIFO (stats->stat.st_mode))))
{
if (file)
close (desc);
return 1;
}
