Potential OpenCL Spec Error in 3.2.4

[EJainDev]

OpenCL specification says the following in section 3.2.4:

For example, if a work-group function occurs within a loop, the work-items must encounter the same sub-group function in the same loop iterations.

Is it supposed to say sub-group function instead of work-group function or is that intended?

Yes, good catch! I'll fix this.

I'll also try to remove some of the duplicated text between this paragraph and the preceding paragraph about work-group functions.
