bug#45007: VC-log helpful modeline information not adapting to scope

[tomasn]

Hello Buglist

In the emacs repo, say, visiting INSTALL.REPO

C-x v l (vc-print-log)

gives me a log and a helpful message on the mode-line:

Git-Log-View from INSTALL.REPO

Helpful because indeed it logs changes that touch INSTALL.REPO.

Visiting the same file again and

C-x v L (vc-print-root-log)

Shows the same message in the log buffer and it seems less helpful
because now I see the log for the root of the repo.

It has been seen in emacs master from April.

Best regards
