This is working as expected.
Some people even stick files named e.g. --interactive into their
directories to use this as some kind of defense against accidental
deletion.
Most programs provide a -- command line option that says "further
arguments should be interpreted as files". But this kind of surprising
experience is inevitable in operating systems that don't formalize
command options separately from file arguments.

Title:
File name beginning with a dash used as program argument
Status in “bash” package in Ubuntu:
Invalid
Bug description:
I mis-typed a tar command and ended up with a file with the name
beginning "--". After a few minutes of confusion and re-typing the
command I noticed the offending file and was given another error when
I tried to rm the file.
It is reproducable using any command eg.
tim@pc1:~/test$ ls
--bork file1 someotherfile
tim@pc1:~/test$ ls *
ls: unrecognised option '--bork'
Try 'ls --help' for more information.
tim@pc1:~/test$ rm *
rm: unrecognised option '--bork'
Try 'rm ./--bork' to remove the file ‘--bork’.
Try 'rm --help' for more information.
tim@pc1:~/test$ tar cvzf ../test.tar.gz *
tar: unrecognised option '--bork'
Try 'tar --help' or 'tar --usage' for more information.
I did notice that rm suggests a solution to the problem, but maybe
this has security implications.
