fts: reduce two or more trailing slashes 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
