|13670  |Change ACCEPT_LICENSE evaluation so that things like ACCEPT_LICENSE="* -@EULA"    |
|zmedico|will work as expected. The ACCEPT_LICENSE variable is now treated as a lazily     |
|       |evaluated incremental, so that * can be used to match all licenses without every  |
|       |having to explicitly expand it to all licenses. It should now behave as approved  |
|       |by the council in response to the "RFC: ACCEPT_LICENSE default value (GLEP 23)"   |
