I made a change to last.c in this package to print out login names
greater than 8 bytes for those systems that define UT_NAMESIZE larger
than 8 bytes.
On a few systems I admin I have a number of login names greater than 8
bytes and I need to have a utility that can show the full login names,
at least up to UT_NAMESIZE.
Thanks. Bob
