Subject: Use b:undo variables correctly

Setting or adding to b:undo_indent and b:undo_ftplugin variables, which
I only learned about just now, allows me to avoid the _GLOBAL.vim hack
and remove some files from both vim/indent/ and vim/ftplugin/.

These variables aren't subjected to :execute automatically in anything
older than Vim 7.0, but I don't think that's too much of a concern as
the only real reason they're needed are for changing filetypes in the
same buffer, which doesn't happen that often anyway.
