show-index: the short help should say the command reads from its input

Browse Source 
The short help text given by "git show-index -h" says

    $ git show-index -h
    usage: git show-index [--object-format=<hash-algorithm>]

        --[no-]object-format <hash-algorithm>
                              specify the hash algorithm to use

The command takes a pack .idx file from its standard input.  The
user has to _know_ this, as there is no indication from this output.

Give a hint that the data to work on is fed from its standard input.
