Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
A new module is added to jj_lib which exposes a function get_annotation_for_file. This annotates the given file line by line with commit information according to the commit that made the most recent change to the line. Similarly, a new command is added to the CLI called `jj file annotate` which accepts a file path. It then prints out line by line the commit information for the line and the line itself. Specific commit information can be configured via the templates.annotate_commit_summary config variable
