Re: bug report

It does not warn me in this case. I replayed it again, below is my process:

$ mkdir bug_test
$ cd bug_test/
$ git init
Initialized empty Git repository in /home/libenchao/tmp/bug_test/.git/
$ echo 'hello' > README.md
$ git add README.md
$ git commit -m 'Add README.md'
[master (root-commit) 9cdb3a8] Add README.md
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ git checkout -b A
Switched to a new branch 'A'
$ echo 'world' >> README.md
$ git commit -a -m 'Add one line'
[A 6f0b0a3] Add one line
 1 file changed, 1 insertion(+)
$ git checkout master
Switched to branch 'master'
$ git checkout -b B
Switched to a new branch 'B'
$ echo 'world' >> README.md
$ git commit -a -m 'Add one line too'
[B d89cf11] Add one line too
 1 file changed, 1 insertion(+)
$ vim README.md                        # in this line, I modify line 2
'world' to 'git'
$ cat README.md
hello
git
$ git commit -a -m 'Modify one line'
[B a674427] Modify one line
 1 file changed, 1 insertion(+), 1 deletion(-)
$ git checkout master
Switched to branch 'master'
$ git merge A
Updating 9cdb3a8..6f0b0a3
Fast-forward
 README.md | 1 +
 1 file changed, 1 insertion(+)
$ git checkout B
Switched to branch 'B'
$ git rebase master
First, rewinding head to replay your work on top of it...
Applying: Modify one line
$ cat README.md
hello
git
$
