Create the repository:

▶ git init

Create the first branch:

▶ echo foo > one
▶ git add one
▶ git commit -m A
[master (root-commit) 7edac5e] A
 1 file changed, 1 insertion(+)
 create mode 100644 one
▶ echo bar > two
▶ git add two   
▶ git commit -m D
[master 68c3082] D
 1 file changed, 1 insertion(+)
 create mode 100644 two
▶ ls
one  two

Create the second branch, where the initial commit (K) is the same as the final commit of master (D), except that a file has been deleted:

▶ git checkout --orphan other 
Switched to a new branch 'other'
▶ git add one
▶ git rm -f two
rm 'two'
▶ git commit -m K
[other (root-commit) 4fe7f5c] K
 1 file changed, 1 insertion(+)
 create mode 100644 one
▶ echo baz > three
▶ git add three
▶ git commit -m N
[other d388bc3] N
 1 file changed, 1 insertion(+)
 create mode 100644 three
▶ ls
one  three

Merge the branches using git rebase.

▶ git checkout -b merged                              
Switched to a new branch 'merged'
▶ git rebase --onto master --root
First, rewinding head to replay your work on top of it...
Applying: N
▶ ls
one  three  two
▶ git log --oneline merged
aa0e3f6 N
68c3082 D
7edac5e A

Note that the commit, K, that deleted file "two" has been eliminated, and "two" is incorrectly present in the merged branch even though it did not appear in "other" branch.

The full logs, for the curious:

▶ git log -p master
