It was my mistake. git-commit -a adds files which are tracked.
Currently README.md is not tracked. So you will have to first use
git-add to add them for tracking. Though while trying out your steps I
used git-add. For further commits one can use -a with git-commit.

You are technically not adding a line. You are modifying the previous
line to the updated line. So the contents of the file will be:
"world"
It seems from the further part that you actually wanted to add the
line rather than modifying it. Better to use ">>" instead of ">". ">>"
is used for appending.

I think you mean modify.

The git behavior is quite correct.
When you are on the B branch and you choose to rebase it on the
master, it will apply commits as patches. So it first sees that the
commit on the A branch which is now merged with master ie. "Add one
line" and the commit on the B branch "Add one line too" are doing the
same thing which is removing the line "hello" and adding the line
"world". Then it applies the commit "modify one line" on top of this
which removes the line "world" and adds the line "git". So finally,
README.md will contain only "git".
