steps to create
add a file in a branch with a line (or more).
create a new branch based on this branch and check it out.
in the new branch mv the file into a directory with the same name as
the file was. add -u and add the file so git sees the rename.
checkout the original branch add some lines. checkout the new branch
merge. the merge will go fine.
remove a line from the new branches file.
checkout master. add another line to that file.
checkout new branch and attempt to merge.
you should now see the point that may test case is at.
Yes, this is because automatic renaming detection fails
with this kind of toy examples. Git can't infer the file
was renamed because almost nothing is similar enough. Take
a look at the attached script and run it with 'sh test.sh'
and 'sh test.sh real_test', and look at the difference.
