Possible typo in git stash doc page

Hi,

In the doc page about git stash, specifically where there're the
details about git stash push
https://git-scm.com/docs/git-stash#Documentation/git-stash.txt-push-p--patch-S--staged-k--no-keep-index-u--include-untracked-a--all-q--quiet-m--messageltmessagegt--pathspec-from-fileltfilegt--pathspec-file-nul--ltpathspecgt82308203

There's a reference about --staged or -S. I tried to execute the
command with that flag and the output is like this one:

error: unknown switch `S'
usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
          [-u|--include-untracked] [-a|--all] [-m|--message <message>]
          [--] [<pathspec>...]]

    -k, --keep-index      keep index
    -p, --patch           stash in patch mode
    -q, --quiet           quiet mode
    -u, --include-untracked
                          include untracked files in stash
    -a, --all             include ignore files
    -m, --message <message>
                          stash message

Even if the flag is --staged

error: unknown option `staged'
usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet]
          [-u|--include-untracked] [-a|--all] [-m|--message <message>]
          [--] [<pathspec>...]]

    -k, --keep-index      keep index
    -p, --patch           stash in patch mode
    -q, --quiet           quiet mode
    -u, --include-untracked
                          include untracked files in stash
    -a, --all             include ignore files
    -m, --message <message>
                          stash message

At the start of the same page, --staged is not present in the push
arguments, so I think that is a typo.

Have a good day
