[RFC] vim-patch: Mark patch 7.4.560 as NA

Mark patch 7.4.560 as NA

The memory leak fixed in 7.4.560 was fixed in e10670ac3bccbea707432bdb54e18639cf2e125f. We also do not need to keep `y_current->y_array` as is until done, because our memory allocations cannot fail.

Problem:    Memory leak using :wviminfo.  Issue 296 .
Solution:   Free memory when needed. (idea by Christian Brabandt)
