Issue Description:

Bug occurs on fedora 24 after building swift from source with https://github.com/thawkins/fedora-swift And on Arch Linux when building from source with https://github.com/RLovelett/swift-aur.

Text can be deleted as intended until you enter any text and hit return then each character can only be replaced or deleted by going through repl history.
1> let a=3
a: Int = 3
2>
input any thing at 2> ,then it will can't be cleared by Backspace(still showing)

Duplicate of https://bugs.swift.org/browse/SR-15369.

I'm marking these as dups so we can concentrate the discussion on a single issue. It has been fixed on main for a while, but unfortunately i missed the window to cherry-pick it into 5.5. If you're able to, please download the main snapshot on https://www.swift.org/download/, verify if it's working for you and letting me know on the SR-15369.
