Description:
When using pm-utils to suspend automatically on lid close (by adding /usr/sbin/pm-suspend to the "button/lid" match in the case statement within /etc/acpi/handler.sh), the laptop suspends immediately after resuming when the lid is opened.

Additional info:
* package version(s)
acpid 2.0.12-1 with linux 3.1-4 and 3.1.1-1.

* config and/or log files etc.
/etc/acpi/handler.sh

Steps to reproduce:
Add the following line to the "button/lid" section of the case statement:

logger -t acpid "button/lid triggered. Arguments: $@"

Close the lid, open it, and grep the appropriate log for "acpid". You'll notice that there will be two events that were logged:

button/lid LID close
button/lid LID open

As both start with "button/lid", both trigger that event in /etc/acpi/handler.sh.

I've attached a patch that checks argument #3 to differentiate between open and close events.

And I just realized that I reversed the commented out messages in the part that I added. Fail! :)

Oh well, I think you get the idea.
