I have new repository called myrepo and I have master branch with two previous commits, the first commit with a file1.txt and second commit with a file2.txt.
After the second commit, created a new branch called file2Split.
After that I realize that file2.txt is too big, how I want to split
its content by creating a new file2a.txt, and then commit the
myquestion is how can I automerge modifications in the same files.
