I think it does keep the current line (by number).

But the exact text can shift up or down between revisions, so we end up 
hunting for it.

It might be possible to keep up with the hunks by doing full diff before 
switching the revision, then count removals/additions in preceding hunks 
and go there. But it would not work when 'a' brings you to the version 
of the file before it was renamed, for example.
