[Foundation-l] cheatsheets: proofreaders wanted

[quiddity]

At http://en.wikipedia.org/wiki/Wikipedia:Cheatsheet (the current
target of the "[[Editing help]]" link seen in edit-mode)
we decided to exclude a few of those commands, such as ----
(horizontal line) because its use is deprecated, and ~~~ (3 tilde sig)
because it is rarely used.

We also added instructions for <ref> tags, and
::talkpage-text-indents. Because they are (hopefully) used frequently.

Perhaps some of those changes might be useful in the pdf-cheatsheets?
