As an aside, I think it's a bad idea to put colons in filenames anyway.

(And yes, variables are expended by the shell; wget can't tell the 
difference between stuff you typed in and stuff the shell expended from 
an environment variable. So if it doesn't like it when you type it, it 
won't like it when the shell types it.)
