Oh, it's in `My account'!  I found `Documents' there at last. :)
After some trials, I realized w3m doesn't support the `disabled'
attribute in forms unfortunately.  But it supports a similar one,
the `readonly' attribute.  So, I determined to go this way:

Add a filter function to `w3m-filter-configuration'.  It's a
function that replaces `disabled' with `readonly' in an html
source before rendering it.

It was partly successful, but I feel like improving a user
interface for readonly/disabled textarea more.  Maybe it takes
one more day.  As for the other issues, I'm going to deal with,
afterward.
