It's not practical to run nix repl nixpkgs and only get "Added 6 variables". This does not tell me which variables. I have to run the output against a plain nix repl, perform tab completion, and then diff these two outputs.

I'd like to just print the variables which were just loaded into the global scope.

@pbsds Good point. Perhaps we should add a command for getting the most recently loaded variables and show these in a pager.

nix repl: Add :ll to show all recently loaded variables

Invoking `:ll` will start a pager with all variables which have just
been loaded by `:lf`, `:l`, or by a flake provided to `nix repl` as an
argument.

@kstrafe
nix repl: Print which variables are just loaded
e3c6451 
When we run `nix repl nixpkgs` we get "Added 6 variables". This is not
useful as it doesn't tell us which variables the flake has exported to
our global repl scope.

This patch prints the name of each variable that was just loaded. We
currently cap printing to 10 variables in order to avoid excessive
prints.
