I assume that you added the setting of b:undo_ftplugin to your ~/.vim/ftplugin/text.vim and you are still seeing 'expandtab' set in help files. The problem is that b:undo_ftplugin is also being set in $VIMRUNTIME/ftplugin/text.vim and since that file is sourced after your ~/.vim/ftplugin/text.vim, its setting is overriding yours. The solution is to put your text.vim file into ~/.vim/after/ftplugin so that it is sourced after $VIMRUNTIME/ftplugin/text.vim and than add the following to your text.vim: if exists("b:undo_ftplugin") let b:undo_ftplugin .= " | setlocal expandtab<" else let b:undo_ftplugin = "setlocal expandtab<" endif Yes, the documentation should be updated.
