Sometime you seem to need to run tset to get a decent termcap
in the environment.  I don't know whether this is a plum 
bug or whether it's a perl termcap lib bug.  Don't set TERMCAP
to a filename.

You can't type control characters to the input line functions.

The folder listing never gets updated once it's made.

The code command doesn't work anymore.   You have to use autoload
or source.

You can't enter an empty folder.  In fact, you can get into an
infinite loop between two empty folders.

We should be smarter about redrawing the screen.  Probably should
have used curses to start with.

Don't type :source and then hit return.

You can refile into the + folder.
