If I get you right, you want a simple merge of two branches with no
common ancestors. Here's a line-by-line sh example with project A in
directory A and project B in directory B, and B will be merged into a
subdirectory "project-b" in A:

  # change to B's directory
  cd B

  # create the subdirectory where B's files will be in A
  mkdir project-b

  # move all files into project-b
  git mv -k * project-b

  # probably check if this worked for you
  ls
  git status

  # commit
  git commit -m "Move all files into subdirectory for inclusion into A"

  # change to A's directory
  cd ../A

  # fetch and merge B into A
  git pull --no-rebase --allow-unrelated-histories ../B
  # ... change commit message to something more meaningful ...

That's it.

If B is public you might want to replace its last commit by some commit
that adds a note that further development is going on in A.
