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