[patch] Fix several documents

[h_east]

Hi Bram and list,

Several documents were pointed out by some Japanese Vim users.
I report this with a patch.

gui_x11.txt
- I made `Example 3` a Header highlight just like Example 1 and 2.

autocmd.txt
- Add `DiffUpdated` to *autocommand-events*

options.txt
- Change `reset` to `off`. Because "reset" is likely to be misunderstood as default "on".

eval.txt
L2464:
- L2464: term_start() returns the buffer number.
L2478~L2479:
- Change Space to Tab. (like the other lines)

Thanks, included most of it.

Using "set" and "reset" is consistent with other remarks about
defaults.vim.
