Comment:
Yes, that is the intended behavior of `getLine`.
One fix to the problem you've described is to set `stdin` to
`LineBuffering`, using `System.IO.hSetBuffering`. On some platforms that
will enable the delete key, but probably not the arrow keys.
If you want full interactive behavior for line input, you will need to use
a package such as [http://hackage.haskell.org/package/haskeline haskeline]
or [http://hackage.haskell.org/package/readline readline].
