can't deal this kind of files, '-filename'

[Lee Huan Chul]

for example

#include <stdio.h>

int main(int argc, char **argv)
{
if (!creat("-file", 0755)) {
printf("creat error\n");
exit(1);
}
}


make file of which name is "-file" and do "ls *file"
then error occures like this

ls: invalid option -- e
Try `ls --help' for more information.

this is because coreutils uses raw argv(in main) as getopt's argument(in
decode_switches, ls.c:1371).

of course if using "ls $PWD/*file", then it works well.

i tried with coreutils-4.5.3-19 and coreutil-5.0.

sorry for poor English.
thanks for reading.
