Sorry for bringing an old thread back to life, but imo this needs some
more attention.

It's a valid HTML input name attribute character [1] and imo the
replacement feature (where ' ' and '.' characters are replaced to '_')
should be removed in PHP 6, when the register_globals feature is removed.

There will be PHP applications that need changing, but I estimate that
it will be fixed easily. And since PHP 6 is breaking a lot anyway, what
other version would be more suitable to change this.
