Good point. I'm too used to projects generating their changelogs from git/darcs
logs. Maybe we could start doing something like this for dbus too at some
point?

I actually spoke to Thiago on irc a bit before creating this patch. And he
said the only reason dbus-launch didn't have this behaviour yet, is because the
code was so confusing. I'll see if any reasoning against this in the initial
discussion though.

I actually did the patch to make the actual code changes as minimal as
possible, because of this. I'm pretty sure that i didn't change any behaviour
apart from the intended change, but i will also admit that i have no clue what
large parts of the (existing) code actually do.

I guess it would be good if someone at some point could reverse-engineer
and refactor dbus-launch to be more maintainable...

Will do

Thanks for the comments,
