Ability to abort requests

[TehShrike]

welp, I'm in a place where I need to abort requests sometimes.

• node: request.destroy()
• XHR: request.abort()
• fetch: you pass in a signal that's a new AbortController() that you can abort later or whatever

it would be cool if httpie exposed a cross-platform method for aborting a request.

But is it cool enough for lukeed to add it? 🤔
