The ./ breaks the function if you give it absolute pathnames.  Replace
this last line with cat -- "$arg" instead.

A "clever" version of this part of the function that does something
similar in a more compact form is:

tail -n +1 -- "$@"

I didn't write that and can't claim credit for it, but I don't know who
did, so I can't give appropriate credit either.
