Summary:                    chgrp with no arguments reports argument list for
chown
Description: 
chgrp_main() should abort before even calling chown_main() when no or
incorrect arguments are present, otherwise you list out arguments that are
not used by chown.

Can you give an example? It works for me:

# ./busybox chgrp
BusyBox v1.7.0.svn (2007-06-30 12:02:05 CEST) multi-call binary

Usage: chgrp [-RhLHPcvf]... GROUP FILE...

Change the group membership of each FILE to GROUP

Options:
        -R      Recurse directories
        -h      Affect symlinks instead of symlink targets
        -L      Traverse all symlinks to directories
        -H      Traverse symlinks on command line only
        -P      Do not traverse symlinks (default)
        -c      List changed files
        -v      Verbose
        -f      Hide errors

# ./busybox chown
BusyBox v1.7.0.svn (2007-06-30 12:02:05 CEST) multi-call binary

Usage: chown [-RhLHPcvf]...  OWNER[<.|:>[GROUP]] FILE...

Change the owner and/or group of each FILE to OWNER and/or GROUP

Options:
        -R      Recurse directories
        -h      Affect symlinks instead of symlink targets
        -L      Traverse all symlinks to directories
        -H      Traverse symlinks on command line only
        -P      Do not traverse symlinks (default)
        -c      List changed files
        -v      List all files
        -f      Hide errors

No... you don't understand.  All of the listed options for chgrp are not
needed, nor do they work for chgrp.  Why display them?

In fact, the only option that should be listed for chgrp is -R, since it's
the only one that actually works for that.

Bleh... ok... I've got to get with the other people here and have them be a
bit more clear with things.

Anyway, in 1.4.2, -c does not work as expected.

What option does not work? Let me check...

# ./busybox chgrp --help
BusyBox v1.7.0.svn (2007-07-01 20:20:44 CEST) multi-call binary

Usage: chgrp [-RhLHPcvf]... GROUP FILE...

Change the group membership of each FILE to GROUP

Options:
        -R      Recurse directories
        -h      Affect symlinks instead of symlink targets
        -L      Traverse all symlinks to directories
        -H      Traverse symlinks on command line only
        -P      Do not traverse symlinks (default)
        -c      List changed files
        -v      Verbose
        -f      Hide errors

# mkdir zz
# ln -s zz zzl
# >zz/file
# ./busybox chgrp -Rv 1 zz
changed ownership of 'zz' to 0:1
changed ownership of 'zz/file' to 0:1
# ./busybox chgrp -Rv 2 zzl
changed ownership of 'zzl' to 0:2
# ls -ld zz zzl
drwxr-xr-x    2 root     1              72 Jul  4 20:48 zz
lrwxrwxrwx    1 root     2               2 Jul  4 20:47 zzl -> zz
# ./busybox chgrp -RvL 3 zzl
changed ownership of '/.1/usr/srcdevel/bbox/fix/busybox.t5/zz' to 0:3
changed ownership of '/.1/usr/srcdevel/bbox/fix/busybox.t5/zz/file' to
0:3
# ./busybox chgrp -RcL 4 zzl
changed ownership of '/.1/usr/srcdevel/bbox/fix/busybox.t5/zz' to 0:4
changed ownership of '/.1/usr/srcdevel/bbox/fix/busybox.t5/zz/file' to
0:4
# ./busybox chgrp -RcL 4 zzl
# _

Well, apart from -L unexpectedly giving fully-resolved names, at least -R
-c -v -L seem to work.
