git使用Beyond Compare作为diff和merge工具

git pull或merge产生冲突时需要手动解决冲突，使用BeyondCompare可以较方便地完成该项工作。WSL下git配置如下：

$  cat ~/.gitconfig

[i18n]
        logoutputencoding = utf-8
[user]
        email = chudongyu@corp.xxxx.com
        name = chudongyu
[core]
        editor = vim
        autocrlf = input
[difftool "bc4"]
        cmd = "\"/mnt/d/Program Files/Beyond Compare 4/BCompare.exe\" \"$LOCAL\" \"$REMOTE\""
[merge]
        tool = bc4
[mergetool "bc4"]
        cmd = "\"/mnt/d/Program Files/Beyond Compare 4/BCompare.exe\" \"$BASE\" \"$MERGED\""

git difftool
git mergetool

产生冲突后，使用git mergetool，git会使用bc4逐个打开冲突文件让你解决。所有冲突文件处理后git merge --continue或正常add后commit即可。
