I know it's not what you meant, that's why I said "another suggestion".
I don't think that we should add another config variable to workaround a
PHP bug. Config variables add to complexity, and most users don't read 
the doc.

The current is_upload philosophy avoids displaying the file selector
if we cannot detect that uploads are allowed. So if we reverse the 
logic, we will avoid displaying the file selector if we detect that
uploads are not allowed, and sometimes (where PHP is < 43000 and
ini_get() is not available), we will display a file selector that
won't work. I think that this is acceptable.
