Actually, Brian Kernighan and Rob Pike suggest such a program (shell
script) in 'The Unix Programming Environment'.  Basically, it invokes
print with an argument of -$0 -- that is, if invoked as '2' it filters
its stdin into 2 columns, if invoked as '3' into 3 columns, ...  To
'implement' a new number of columns you just add another link to the
script.  Doesn't half pollute your ~/lib namespace ...
