I'm not asking about how to remove the file (thanks, anyway, although
I see the how-many-ways-to-do-so discussion is starting up again): I'm
just saying that "while you're at it [ie, `fixing' rm *]", you as might
as well consider the problem of the user who wants to remove some of his
files, and types "rm -i *", expecting to get interactive prompting, and
instead has all his files removed.  If the first file is "-f", you now
have one unhappy user.

"rm -i -- *" will avoid this problem, but I don't expect a lot of people
to get into the habit of typing "--" here and in similar situations.
