Look at the 2.4.5 implementation, perhaps.  A combination of a modified
read_file() + input_to() functionality.

Both work, but for really large files I'd recommend against editor
because it needs to read in the entire file before being able to do
anything.  Rather laggy.

I suggest you look at the get_dir() kfun.

So what do you do for files larger than the maximum string size? :-)
