Autocomplete insert vs. overwrite

[bazhenov]

First of all, thank you very much for your work. I must say zed is one of the most pleasant experiences I have in coding for last several years. It's freaking fast, and I very like editor is not to staying in my way. Great job!

Right now (zed 0.76.1) when press Enter or Tab in autocomplete, selected item overwrites the item next to it (if there is no whitespace to the right of the cursor). In previous zed version item was appended. I think it would be useful to have both strategies available.

For example in IntelliJ IDEA Enter is inserting text Tab is overwriting.
