Ah, you found very old problem.
Last patch also have:
- multiple "-u unsetenv" support
- GNU long option support
- save errno after exec failed before bb_perror_msg()

Hello all,
This patch adds more "Help" text to the config system. Almost
all applets now have a help entry. Also, I cleaned up the spacing of
the existing text so that things are consistent. This patch is against
this morning's CVS.

Latest BusyBox from CVS (Jul 7 2003).
File coreutils/ls.c
"if" at line 970 should be enclosed in #ifdef CONFIG_FEATURE_LS_SORTFILES
"if" at line 976 should be enclosed in #ifdef CONFIG_FEATURE_LS_TIMESTAMPS
"rootfs" entry as well as the traditional "/dev/root" entry. This caused
applets such as mount and df to display two root filesystem entries....
This teaches the relevant utilities to ignore the "rootfs" entry.

Manuel,
I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.
$ echo a b | busybox grep -e a b
a b
a b
But right is printing one only.
