Helped-by: Đoàn Trần Công Danh Helped-by: David Aguilar Signed-off-by: Lin Sun Signed-off-by: Junio C Hamano --- Enable auto-merge for meld to follow the vimdiff beharior Hi, the mergetool "meld" does NOT merge the no-conflict changes, while the mergetool "vimdiff" will merge the no-conflict changes and highlight the conflict parts. This patch will make the mergetool "meld" similar to "vimdiff", auto-merge the no-conflict changes, highlight conflict parts.
