The thing is, leading '-' is perfectly legal for a POSIX filename.  
Which is why getopt and other bog-standard cmdline parsing libraries 
implement the special '--' option to signify that subsequent arguments 
are filenames rather than options.

This quirk of shell wildcard expansion/ambiguity isn't anything new, 
especially to anyone who has had to work with real-world-supplied 
filenames.
