How to submit patches?

Hi,

I've written some patches to screen over the past year to make it work
more to my taste. Perhaps some of these might be useful, but I don't
know how to package them up. Could you please give pointers on that?
Thanks.

Anyway, the patches are:
1. Ability to choose alphanumeric window "numbers", much like irssi's
window handling. This is implemented with a "labels" command and
keybindings assigning C-a <letter> to select <letter> where
appropriate. For instance, they are defined in my screenrc as:
labels          "0123456789qwetuiofgjvbmERTYUIOPDGHJKLCVBM"
For each of them, there is also a line, such as:
bind q select q
The missing letters are the ones I actually use for screen commands.
This lets me toggle between windows very quickly...

2. A mode like mapdefault but persistent; this is so I can launch
embedded screen instances on other hosts and interact with them
naturally. This is implemented with two commands, mapoff and mapon.
Relevant lines:
defflow off
bindkey         "^S"            eval "mapoff" "escape ^Ss" "echo \"No
mappings applied (use \\\^S\\\^Q to revert)\""
bind            "^Q"            eval "mapon"  "escape ^Aa" "echo \"All
mappings applied\""
I just type ^S to enter the mode (but I can still use ^S as an escape
character if I need to on my local session) and ^S^Q to exit it.

Well, if you don't consider the patches useful, don't bother to give
pointers on how to submit them. ;) By the way, they're all for
4.00.02.
