"git apply" was not very careful about reading from, removing, updating and creating paths outside the working tree (under --index/--cached) or the current directory (when used as a replacement for GNU patch). * jc/apply-beyond-symlink: apply: do not touch a file beyond a symbolic link apply: do not read from beyond a symbolic link apply: do not read from the filesystem under --index apply: reject input that touches outside the working area
