This is not a bug.

Perhaps a RFE, to add a shopt that prompts the user when filenames that look like options are expanded.

Severity should be 1 - Wish

I also have this problem. This is a really annoying bug. I couldn't figure out what the problem was at first. After some tries I realized that the problem was a file whose named started with '-.' .

I think to fix this properly C way of handling main will have to be changed.

Issue is nasty.

rm -i *  Seams fine until in the directory there is a file -rf as first file and deletes everything in the directory.

or cat * and it hits a file called -.

Over and over again user can expect one thing to happen yet the shell does something completely different.

This is not userfriendly.  Means training users to use ./*

The POSIX solution is.
POSIX.1-2008 ’s “base definitions” document section 4.7 (“Filename Portability”) specifically says “Portable filenames shall not have the <hyphen> character as the first character since this may cause problems when filenames are passed as command line arguments”

Linux does not conform to this.  Also other OS's don't conform so we cannot depend on this being the case.
