After 'C-x v g' (vc-annotate), typing 'a'
(vc-annotate-revision-previous-to-line)
doesn't keep the current line. For VC archaeology there is a need to traverse
the history of the current line by typing a sequence of 'a a a ...'
But 'a' doesn't keep the line current, so need to spend time
finding the same line in the buffer to be able to type 'a' on it again.
I think `git blame` provides a --porcelain option that helps track lines
accross revisions. I expect that using that information would be an
improvement over the current behavior, but the solution won't be perfect
and in some situations it'll still go to a strange line. Also, I don't
know if this feature is available in other non-git vc backends.
