Bukkit

Steps to reproduce:
- Place a block with metadata, for example a Applied Energistics crafting terminal 601:3
- ban blockId 601
- add permission for member to use it in Pex:
pex group Member add 'ItemRestrict.bypass.Usage.601-3'
pex reload
- start debug
pex user Lemadec toggle debug
- deop yourself, set you as member
- right click the block

Expected Output:
Block is usable
"ItemRestrict.bypass.Usage.600-6", cache value true found.

Actual Output:
Block isn't usable
"ItemRestrict.bypass.Usage.600-6", cache value false found.
=> I suspect '-' is a regex expression for pex, thus it looks for permissions covering all blocks from 6 to 600...

I will test a setup with PEX tonight.

It appears, its simple regex syntax, you just need to espace the special char like so: ItemRestrict.bypass.Usage.600\-6
