Faster CR -> LF Macro?

[Tim Hubberstey]

I do a large number of tasks, including this one, with a shell "macro".

I find that it is faster by a huge amount than doing things in the macro 
language. I assume this is because the macro language is interpreted 
and, once you "pay" for spawning a shell, the shell filter is native 
code. The only disadvantage is that it makes things less portable. In 
this case all you need is "tr -d '\015'" so there's not much of a 
portability issue.
