Merge branch 'jc/apply-ws-prefix'

Applying a patch not generated by Git in a subdirectory used to check the whitespace breakage using the attributes for incorrect paths. Also whitespace checks were performed even for paths excluded via "git apply --exclude=<path>" mechanism. * jc/apply-ws-prefix: apply: omit ws check for excluded paths apply: hoist use_patch() helper for path exclusion up apply: use the right attribute for paths in non-Git patches
