Do you want this examples added in commit message or in a manpages[1]?

You can test this feature by droping a file wine.conf in /etc/binfmt.d
with the following content:
# Start WINE on Windows executables
:DOSWin:M::MZ::/usr/bin/wine:

After a reboot, or a succeful run of /usr/lib/initscripts/arch-binfmt,
you can run ./toto.exe and it will be lauched automagically with wine
as interpreter.

You can read more detail on this linux feature in the kernel documentation[2].

I don't believe package currently use this feature.

There is a wiki page with example for java[3] where the job is done in
rc.local. This patch will allow to do it by initscripts config.
