Prevent last eshell from being killed, or spawn a new one when equake is launched.#23

In GitLab by @Lockywolf on Jun 30, 2021, 04:42 The test case is the following: 1. Configure equake like this: ``` (use-package equake :ensure t :demand t :bind ("<f12>" . equake-invoke)) ``` 2. Start Emacs 3. Press F12 4. C-x k RET Now the only eshell buffer is killed, and equake starts displaying ordinary Emacs buffers. Any subsequently created eshells do not get into the equake tabs.
