Subject: [PATCH] test_printf: add test for additional escape (\c)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using this escaped character will cause `printf` to stop generating characters.

For instance,

```rust
hbina@akarin ~/g/uutils (hbina-add-test-for-additional-escape)> cargo run --quiet -- printf "%s\c%s" a b
a⏎
```
