When one is browsing a source repository - the context for the OP, IIRC
- one is most likely visiting unmodified files. So a question of undo
does arise.
I think if one wants to visit the point where changes were introduced,
one can use
C-h f highlight-changes-mode
and use the navigation command provided by that mode.
Personally - I mostly work with version controlled files - I use a
combination of
M-x diff-buffer-with-file
and use hunks in diff buffer to provide me a map of places that are of
interest to me.
