As a deployer, when a SpiderPig deploy fails, I want to be able to copy the error output (e.g. into IRC or a Phabricator task).

The console implementation used by SpiderPig (@xterm/xterm?) seems to prevent that; select-to-copy (Unix style) doesn’t copy anything, and Ctrl+C doesn’t copy anything either (but scrolls to the end – I think it gets interpreted as a SIGTERM attempt? but hopefully the console is readonly).
