file_exists generates a "stat failed.." warning when the file is nonexistant.

This has been reported for is_file/dir/ and friends, and sure, it might be a decent thing to do warning on those, but for this function it's simply mindboggling, the whole idea is that i do not know if the file exists or not. And temporarily setting the report level to something that won't print this warning is not just my cup of tea.

Guess I should start preceeding every command with @ (j/k)
