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 Improved by: Eric Blake
