It is very strange to do this via a register. Just use `execute join(fn, "\n")`.

Also note that `let @t=t` does *not* restore register correctly. E.g. try

call setreg('a', ['a', 'b', 'c'], 'b1')
echo getregtype('a') " Echoes ^V1
let @a=@a
echo getregtype('a') " Echoes v: register type is determined
automatically at `let @a` and is never block

. Also

let reg = ["a\n", "b"]
call setreg('a', reg)
let @a=@a
echo reg ==# getreg('a', 1, 1) " Echoes 0: NUL cannot be restored
via `let @a`

.
