Bram is the creator and maintainer of vim and the author of that patch. https://groups.google.com/forum/#!topic/vim_dev/QCj8lIntzCk https://groups.google.com/forum/#!topic/vim_dev/QCj8lIntzCk The space following the "#" is meant to signify that the preprocessor directive is nested one layer deep. You can see that this style is used in other files, like here: https://github.com/vim/vim/blob/master/src/gui.c#L40-L42 https://github.com/vim/vim/blob/master/src/gui.c#L40-L42 So no, I think this is Bram bringing one file's indentation style in line with the rest of the project.
