Add a little implementation of ls(1) so that we can look at all and

only the attributes of files that rsync is meant to synchronize.

+ * tls -- Trivial recursive ls, for comparing two directories after
+ * running an rsync.
+ *
+ * The problem with using the system's own ls is that some features
+ * have little quirks that make directories look different when for
+ * our purposes they're the same -- for example, the BSD braindamage
+ * about setting the mode on symlinks based on your current umask.
+ *
+ * There are some restrictions compared to regular ls: all the names
+ * on the command line must be directories rather than files; you
+ * can't give wildcards either.
+ *
+ * At the moment we don't sort the output, but all the files have full
+ * names, so you can run it through sort(1).
+ *
+ * We need to recurse downwards and show all the interesting
+ * information and no more.
+ *
+ * \todo Use readdir64 if available?
