conflito do git rebase -i -autosquash
O git está me dando uma grande dor de cabeça ao usar --fixup e --autosquash. Gostaria de dar dois exemplos, um funcionando perfeitamente e o outro uma bagunça. (versão 2.6.2 do git)
Exemplo de trabalho:
Primeiro commit:
$ git init
$ printf '1\n' > test.file
$ git add test.file
$ git commit -m 'Insert 1 --> first line'
$ cat test.file
1
Segunda confirmação (BUG):
$ printf 'This is\na BUG\n' >> test.file
$ git commit -am 'Added line 2 and 3 with BUG'
$ cat test.file
1
This is
a BUG
Terceiro commit:
$ sed -i '2i 2' test.file
$ git commit -am 'Insert 2 --> second line'
$ cat test.file
1
2
This is
a BUG
Quarta confirmação (correção):
$ sed -i 's/a BUG/NOT a BUG/' test.file
$ git add test.file
$ git log --oneline
b021696 Insert 2 --> second line
2e18b8d Added line 2 and 3 with BUG
d7b60a1 Insert 1 --> first line
$ git commit --fixup HEAD~
$ cat test.file
1
2
This is
NOT a BUG
Rebase:
$ git log --oneline
fe99989 fixup! Added line 2 and 3 with BUG
b021696 Insert 2 --> second line
2e18b8d Added line 2 and 3 with BUG
d7b60a1 Insert 1 --> first line
$ git rebase -i --autosquash HEAD~3
[detached HEAD 6660b0e] Added line 2 and 3 with BUG

Successfully rebased and updated refs/heads/master.
Exemplo de dor de cabeça: (A única diferença é que o commit do BUGGY é uma única linha)
Primeiro commit:
$ git init
$ printf '1\n' > test.file
$ git add test.file
$ git commit -m 'Insert 1 --> first line'
$ cat test.file
1
Segunda confirmação (BUG):
$ printf 'This is a BUG\n' >> test.file
$ git commit -am 'Added line 2 with BUG'
$ cat test.file

This is a BUG
Terceiro commit:
$ sed -i '2i 2' test.file
$ git commit -am 'Insert 2 --> second line'
$ cat test.file

This is a BUG
Quarta confirmação (correção):
$ sed -i 's/a BUG/NOT a BUG/' test.file
$ git add test.file
$ git log --oneline
2b83fe7 Insert 2 --> second line
62cdd05 Added line 2 with BUG
0ee3343 Insert 1 --> first line
$ git commit --fixup HEAD~
$ cat test.file

This is NOT a BUG
Rebase:
$ git log --oneline
c3d3db7 fixup! Added line 2 with BUG
2b83fe7 Insert 2 --> second line
62cdd05 Added line 2 with BUG
0ee3343 Insert 1 --> first line
$ git rebase -i --autosquash HEAD~3
error: could not apply c3d3db7... fixup! Added line 2 with BUG
When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

Por que a correção não se aplica corretamente?
Por que a correção também contém "2", que não deve estar no patch introduzido pelo patch, mas no patch do commit anterior.
