28 * We need to keep track of how symlinks in the preimage are
29 * manipulated by the patches. A patch to add a/b/c where a/b
30 * is a symlink should not be allowed to affect the directory
31 * the symlink points at, but if the same patch removes a/b,
32 * it is perfectly fine, as the patch removes a/b to make room
33 * to create a directory a/b so that a/b/c can be created.
34 *
35 * See also "struct string_list symlink_changes" in "struct
36 * apply_state".
