Edit The Current Command Prompt
A neat feature of bash is the ability to open whatever the current state of
the command prompt is into your default editor.
Let's say we have a really long command that we've just tried to run, but it
failed and we need to make a small change somewhere in the middle. Instead of
holding the left arrow key for 30 seconds, we can instead hit CTRL-X CTRL-E.
This pops us into our EDITOR (or maybe VISUAL, not sure which). In my case,
that is nvim. I now have access to all the features I'm used to in nvim for
quickly navigating to and editing, searching and replacing, or whatever.
Once I've got the command how I like it, I can save and exit (:wq) and the
updated command will be executed.
This is similar to the fc builtin,
which also happens to be available for zsh.
