## Summary  
Prevent undo grouping when an LSP completion includes extra edits so
that the completion and its extra edits are applied and reverted
atomically.

## Problem
When applying an LSP completion that also applies extra edits, the
editor may merge that completion into the surrounding undo group or
split the transaction while waiting for edits, causing undo to leave the
buffer in an inconsistent state.

## Solution
* Always block undo merging for completions

Closes #ISSUE

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
