For readability, can you put the <h3> block on a new line?

[Mike Mammarella, 2011/05/22 00:35:11]

Done.

+    <div id="password-search-column">
+      <input id="password-search-box" type="search"
+          placeholder=" Search passwords" incremental

What's the space at the beginning of the placeholder for?

[Mike Mammarella, 2011/05/22 00:35:11]

Makes it look nicer. There's a magnifying glass icon in search boxes and this
puts some space between it and the placeholder.

Though really if it's supported we should do
i18n-values="placeholder:searchPasswords" and a similar thing in the search
field for cookies, but I'd prefer to do that in a follow-up change.

Yes, please; very important for i18n. Do we do the extra space trick in other
instances of the search input?  Is there a styling solution available?
