RE: [PATCH v6] Support auto-merge for meld to follow the vim-diff behavior

[<lin.sun@xxxxxxx>]

Hi Junio,

Thank you for your comments, and the changes are made to follow your suggestion. 
In the [PATCH v7], the ":+set" is removed, and the "${var,,*}" is used to convert 
configuration to lower-case, it won't call git config twice for getting `useAutoMerge`.

Please review again, thank you.
