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.
