If the user selects pretty-printing (-p) the contents of any
dictionaries in the output are sorted by key.

This script has not seen a patch that was specifically for this script
since it was moved to this location in 2013, and I doubt it is used. It
uses "man qmp" for its help message, which does not exist. It also
presumes there is a manual page for qmp-XXX, for each defined qmp
command XXX. I don't think that's true.
The format it expects arguments in is something like:
block-dirty-bitmap-add --node=foo --name=bar
and has no capacity to support nested JSON arguments, either.
Most developers use either qmp-shell or socat (or pasting JSON directly
into qmp stdio), so this duplication and additional alternate syntax is
not helpful.
Remove it. Leave a breadcrumb script just in case, to be removed next
release cycle.
