💜 DESCRIPTION 💜

okay so this function is giving "two jobs, one icon" — it combines tty_insert_flip_string and tty_flip_buffer_push into one call 🔥. The one exception, the little twist, is that it properly holds port->lock 😌.

bestie listen — this one is to be used only internally (by pty currently). Not for you and your little out-of-tree module, fr fr 💀
