Hi,
I've fixed also the issue of whoami cutting down usernames.
This time I cannot send a diff because i don't know if my previous patches will be applied
or not, so I send in the whole file.
The changes I've made don't affect size but ensure that usernames of whatever lenght
are correctly displayed.
root@localhost:/dev/pts/3:/root/Desktop/busybox/coreutils# size whoami_orig.o
   text    data     bss     dec     hex filename
    102       0       0     102      66 whoami_orig.o
root@localhost:/dev/pts/3:/root/Desktop/busybox/coreutils# size whoami.o
   text    data     bss     dec     hex filename
     93       0       0      93      5d whoami.o

This should be applied even if the other patches aren't as this matches the behaviour of the  GNU whoami.

Thanks in advance,
Ciao,
Tito
