change zombie flag on existing windows / command name:
According to the manpage "zombie" is the intended commandname.

For my bug #32029 I propose -zl to enable the requested "defzombie lastwindow" option.

Patch attached that adds -zy and -zn options that enable and disable zombie for a particular command, eg:

    screen -zn reset-database.sh

so you don't have to risk hitting 'r' much later and doing something destructive. -zy is also supported for completeness, but it only comes into play if screen is started with -zn.

When zombie is disabled, this has no effect on any behavior.

When zombie is enabled, -zy normally changes nothing and -zn allows the window to be destroyed when the command exits. If screen is started with -zn, any new windows will not be zombies unless started with screen -zy.

I do mostly python programming, this is at the limits of my C abilities. My main question is whether I've correctly updated MSG_VERSION in screen.h; I added msg.m.create.zombie, but I have no idea what's going on in MSG_REVISION and don't know if I need to do anything there.

This patch is also missing a means of changing the zombie flag on existing windows; presumably this will be a command (although also presumably not 'zombie' to avoid breakage, so I don't know where that leaves 'defzombie') but I don't have the time to implement it at the moment. Hopefully I'll have time to revisit later for that & any changes needed on the patch.
