[PATCH] rev-parse: documentation adjustment - mention remote tracking with @{u}

["Tao Klerks via GitGitGadget" <gitgitgadget@gmail.com>]

From: Tao Klerks <tao@klerks.biz>

The documentation explained the conversion from remote branch path to
local tracking ref path for @{push}, but not for @{upstream}.

Add the note to @{upstream}, and reference it in @{push} to avoid undue
repetition.

 '[<branchname>]@\{push\}', e.g. 'master@\{push\}', '@\{push\}'::
   The suffix '@\{push}' reports the branch "where we would push to" if
   `git push` were run while `branchname` was checked out (or the current
-  `HEAD` if no branchname is specified). Since our push destination is
-  in a remote repository, of course, we report the local tracking branch
-  that corresponds to that branch (i.e., something in `refs/remotes/`).
