[development] Form with multiple submit buttons

[Steven Jones]

Hi,

When the browser posts the form back to the web server it only sends
the value of the form elements against their respective names. That
is, the following input

<input type="sometype" value="value" id="some-id" name="some-name" />

would be posted back to the server as
some-name = value.

Since buttons are also posted back in the same way there is not way
for Drupal know which button was pressed if they share the same name
and value.
