If you make a mistake and choose the wrong file in a file input field of a form, it is impossible to clear it. This makes it impossible to make forms which have optional file input fields. Yes, people do make mistakes!

Reproducible: Always

Steps to Reproduce:
1. Create an HTML form with a file input field. eg. <input type=file name="userfile" size=50 value="">
2. Load the HTML form and choose a file
3. Now try to clear the filename
Actual Results:  
I could not clear the filename

Expected Results:  
I should have been able to manually edit the filename in the field, including the choice to give it the empty filename.

Reproduced on Win32 and Linux 64-bit using Firefox 3.6
