Hello, I wrote vimdiff3 to leverage both the power of git's diff3 and vim's diff mode, but commit 0041797449 broke that. Here you can see how it used to work: https://i.snipboard.io/hSdfkj.jpg The added and changed lines are properly highlighted. After I fix the conflicts vim still properly highlights which lines were changed, and even what specific characters were modified: https://i.snipboard.io/HvpULI.jpg Now I get absolutely nothing: https://i.snipboard.io/HXMui4.jpg Additionally, every time I run the command I get an annoying message: "./content_LOCAL_8975" 6L, 28B "./content_BASE_8975" 6 lines, 29 bytes "./content_REMOTE_8975" 6 lines, 29 bytes "content" 16 lines, 115 bytes Press ENTER or type command to continue Because that's what `bufdo` does. After discussing v1 with Fernando Ramos I came up with a different route to fix the issues by reorganizing the code first, and after the code is reorganized for the special case of single window mode, it should be clear that the switch to the old vimdiff mode for vimdiff3 is easy and trivial.
