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
