electric backspace

[ryanprior]

If you see an emoji, you don't necessarily know how many backspaces it'll take to delete it. Could be just one for a Unicode emoji or many for a github-style one. We can eliminate this uncertainty by advising delete to remove the whole emoji, regardless of how many literal characters it contains.

This sounds like a useful feature. I will work on this once the existing bugs are resolved.

In terms of implementation I think advising delete would be tricky since there are multiple ways in which text can be deleted (one example in sp-delete-char) perhaps we can simply advice delete-char but advises can be tricky as such I try to avoid them if possible.

One approach would be to add a local keymap for emoji text.

Hi,

I have implemented this on master. Please give it a try when MELPA builds.
