This is not a bad idea.
Picking the default too high is a bad idea though; login names are
stored in lots of files, e.g. the wtmp, and if you make them
ridiculously long you'll waste a lot of space.
If i recall, BSDI defaults to allowing 16 character login names. Is
there any reason we need to, by default, allow more?
