Unfortunately the POSIX portable filename character set lacks '+'.


Perhaps Apple used "+VERSION" so as to not collide with any portable 

Admittedly, installed filenames like "Etc/GMT+10" already use "+" and 
nobody seems to mind. Though perhaps the people who would mind are not 
using the "etcetera" file (as it's kinda optional) and thus are 
sidestepping the issue.
