udev patch for attributes with trailing spaces in the values

The following patch strips off spaces that are often contained at the end of 
SYSFS_ attributes. (ie lots of printers etc do this).
I'm not sure if this should actually be added to udev but I would be curious 
to hear peoples thoughts as I find it extremly annoying and pointless to have 
to hexdump the sysfs values to check if there are trailing spaces to write 
the various rules.
