[PATCH] w3m-form-input should put readonly input value on kill ring

[Vladimir Sedach <vas@xxxxxxxxxx>]

Hello,

If you have a readonly input with a short size, like this:

<input type="text" value="a long string" size="3" readonly />

There is no quick way to copy the value of the input. Pressing RET on
the input only displays the message READONLY INPUT in the echo area.

The attached patch makes w3m-form-input put the value on the kill ring
in addition to the echo area. This is similar to what
w3m-print-current-url does.

Vladimir
