Auto-(re)regenerating tags
Simple automatic tags generation with updates on save. This mode provides automatic indexing for Emacs "go to definition" feature, the `xref-go-forward' command (bound to `M-.' by default). At the moment reindexing works off before/after-save-hook, but to handle more complex changes (for example, the user switching to another branch from the terminal) we can look into plugging into something like `filenotify'. Note that this feature disables itself if the user has some tags table already visited (with `M-x visit-tags-table', or through an explicit prompt triggered by some feature that requires tags).
