update replace-message - add support for optional commit ID filter

[bairesearch]

update replace-message - add support for optional commit ID filter: end the line with '@CommitID#' and a commit ID to restrict the replacement expression to a particular commit.

For example;
foo==>bar@commitID#d760d24cf74a0ee68134d4b83a43d1e8ea3b6e1c

Any new progress about this one? I sought for this feature for a while and it turns out this feature is not merged yet.

I'd rather do this similar to the --file-info-callback added in commit 6157207 (filter-repo: add a --file-info-callback, 2024-10-23), where the replace-text is available to the user in combination with both the file name and the file contents in a single callback, and the user can decide based on filename or file contents whether to apply the replace-text changes. Granted, that's in the context of modifying files, whereas this is considering commit messages, but the idea still translates -- make a callback where the user has access to both the commit message, the commit original_id, and the replace-message rules and can choose whether to apply them.
