When I use git difftool to compare 2 history version of 1 file. I met a problem. After I enter the command, it will show hundreds of windows.
> git log --pretty=oneline <file_path>
<commit id0> <name>
<commit id1> <name>
...
<commit id15> <name>
> git diff <commit id1> <commit id5>
<here show difference>
> git difftool -y -x gvimdiff <commit id1> <commit id5>
<then hundreds of widows shows!>
What's the problem?
