graceful exit from "e"

[smichr]

The command "e" prompts for a file name. If this was an accident (like trying to use "e" for "edit" like "i" for "insert") then it would be nice to have a graceful way to cancel the command and continue editing.

Okay, here is what is going on:

• input() doesn't allow for a default value, so input(" > ") will give you a prompt, but you can prefill it with the text to be edited.
• Win32 API code sends keys to input to add the value.
• Error handling is wonky and complains 'can't re-enter readline' when the hook into control-c runs.
• I updated it to just ignore the control C. This doesn't visually undo the edit, but the edit didn't happen.
• The user is stuck in edit mode.

I think I need to unregister the hook that captures control-c for exiting the program when line editing is happening.

I published the hack for the moment.
