cygwin下配置git difftool

主要是配置路径问题，方法摘自网络，修改路径名字

[diff]

    tool = jellybc4
[difftool]
    prompt = false
[difftool "jellybc4"]
    #use cygpath to transform cygwin path $LOCAL (something like /tmp/U5VvP1_abc) to windows path, because bc3 is a windows software
    cmd = \"/cygdrive/c/Program Files/Beyond Compare 4/BCompare.exe\" \"$(cygpath -w $LOCAL)\" \"$REMOTE\"
[merge]
    tool = jellybc4
[mergetool]
    prompt = false
[mergetool "jellybc4"]
    #trustExitCode = true
    cmd = \"/cygdrive/c/Program Files/Beyond Compare 4/BCompare.exe\" \"$LOCAL\" \"$REMOTE\" \"$BASE\" \"$MERGED\" \"$MERGED\"
