Startup script fails on linux when parent directory contains a space character

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Unpack arduino-1.0.1 to a directory with a space in its name. (ie, 
/home/matt/Arduino Class/arduino-1.0.1)
2. Attempt to run the arduino launcher script from the install directory. (ie, 
cd /home/matt/Arduino\ Class/arduino-1.0.1; ./arduino)
3. Watch dirname complain about extra operands.
This behaviour occurs no matter how far removed the space-bearing parent 
directory is from the install directory.

What is the expected output? What do you see instead?
Arduino IDE should launch, but doesn't.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?
Arduino 1.0.1, Ubuntu Linux 12.04 (though I imagine this bug should be 
reproducible on any linux distribution), board doesn't matter - IDE doesn't get 
that far.

Please provide any additional information below.

This is an easy fix. In the arduino launcher script, replace:
APPDIR="$(dirname -- $(readlink -f -- "${0}") )"
with:
APPDIR="$(dirname -- '$(readlink -f -- "${0}")' )"

I've attached a patch to implement this.

The single quotes didn't work for me, but this seems to.
