the help message of the set_password subcommand of the qemu monitor isn't usable

[Karl-Philipp Richter]

`help set_password` in qemu monitor prints `set_password protocol password action-if-connected -- set spice/vnc password` which doesn't allow to figure out how to use this subcommand.

I think the 'help' text in the monitor is only really intended as a brief usage summary reminder (in particular "help" on its own prints the concatenation of all the "help foo" command help, so having "help foo" print a long bit of documentation makes "help" output look weird). The full documentation of each command is in the QEMU documentation proper, which is now at https://www.qemu.org/docs/master/system/monitor.html#commands and where the 'set_password' documentation describes the behaviour more fully.

To make this work in general we'd have to somehow support rendering the rST-format documentation that ends up in the manual as a user response in the monitor, which feels like it would be tricky.
