+ fts: reduce two or more trailing spaces to just one, usually
+ * lib/fts.c (fts_open): Upon initialization, if a name ends in two
+ or more slashes, trim all but the final one. But if a name consists
+ solely of two slashes, don't modify it. If it consists solely of
+ three or more slashes, strip all but one.
+
+ This is part of the solution to a minor problem with rm:
+ it would print a bogus ELOOP diagnostic when failing to remove
+ the slash-decorated name of a symlink-to-directory:
+
+ $ mkdir d && ln -s d s && env rm -r s/
+ rm: cannot remove 's': Too many levels of symbolic links
+
+ With the change below and a trivial don't-trim-trailing-slashes
+ adjustment to remove.c, it does this:
+
+ $ env rm -r s/
+ rm: cannot remove 's/': Not a directory

fts: when there is no risk of overlap, use memcpy, not memmove
* lib/fts.c (fts_alloc): Fix unjustified memcopy: s/memmove/memcpy/
