Truncate mode improvements

[gabrieljcs]

Hi,

Is there a way to "reverse" truncate?
I would like to remove all bytes "above" my cursor instead of "below".
My use case is to remove a stub/wrapper from a file, which I guess would be quite a common use case.

A warning before truncating would probably also be useful given its destructiveness.

Best regards.

This is indeed needed. Will work on this soon. Actually, we need more ways to delete sequences of bytes. I can probably work on a PR to improve the general editing interface.

Thanks for suggesting it!

@gabrieljcs it turns out deleting bytes is harder than it seems, but I did some work on the "reverse truncate" feature you asked for. Take a look: https://github.com/mentebinaria/dz6/tree/improvement/truncate
