git delete-squashed-branches

git delete-squashed-branches deletes branches that have been squash-merged into the current branch. Part of git-extras, it detects branches whose commits were combined and merged as a single commit, which Git's standard --merged flag cannot identify.
Squash merging creates a new commit combining all branch changes, leaving the original branch commits technically unmerged. This causes branch accumulation since git branch --merged won't flag them for deletion. The command uses heuristics to detect when a branch's changes exist in the target branch despite differing commit history.
This tool is essential for platforms like GitHub and GitLab that default to squash merging, where manual branch cleanup becomes tedious.
