WDYM "accidentally"?
At any rate, I think replacing `append' with `cl-union' (or equivalent)
in the code above would be a good idea.

It helps me maintain my additions to `package-archives' in _one_ place
(.emacs) instead of 2 places (.emacs + the command line).

I am not talking about naming, but rather reusing an existing file for a
related purpose.
