[PATCH] add-interactive: reject malformed numerical input

["Seonghyeon Cho (조성현) via GitGitGadget" <gitgitgadget@gmail.com>]

From: Seonghyeon Cho <seonghyeoncho96@gmail.com>

The list-and-choose interface accepts malformed input such as "2m3" and
interprets it as "2-", silently selecting a range to the end. This is
misleading and makes it easy to select unintended items.

Reject such input by treating it as invalid.
