Subject: [PATCH] pvimg: info: Rename '--key' into '--hdr-key' and use '--key'
 as an alias
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename '--key' into '--hdr-key' and use '--key' as an (non-visible)
alias for '--hdr-key' in order to keep the command line backwards
compatible. The chances of someone using '--key' are very low, as this
version has not yet been released by any OS distribution.

This change makes the command line options for the different subcommands
more consistent and therefore easier to use.
