You may want to also check out the "line-level history browser" work by
Bo Yang and Thomas Rast, which is a similar idea, but done much better.

You can find it here:

  http://repo.or.cz/w/git/trast.git/shortlog/refs/heads/line-log-cleanup

or pull it with:

  git pull git://repo.or.cz/git/trast.git line-log-cleanup

Use on a whole file is something like:

  git log -L '1,$':yourfile

But note that it is a work in progress, and I seem to be able to get it
to segfault on some simple tests.

Usually you would graft the tip of the old history to the root commit of
the new history. So it's not a merge, but makes it look like a
contiguous linear history near the graft. But that's only a
per-repository thing. If you want to join two histories in the actual
history graph, you would merge them; if one supersedes the other, then
you would use the "ours" merge strategy to ignore the other side.

I'm not 100% sure I understand your question. Does that answer make
sense?
