# mkdir "bad /"
# ls -l

No / in the name, just a trailing space.  There are ways
to get a / displayed at the end of a directory and subsequent
manipulations on a shell command line will result in
breaking at the space.  Spaces and newlines are both
allowed in filenames and both can cause trouble with
shell scripts.
