And we'd need to do the same for iOS, Android, and OS X, obviously. (I think
it's best to do those in separate patches, if possible.)

File chrome/browser/ui/login/login_prompt.cc (right):

https://codereview.chromium.org/1415243004/diff/1/chrome/browser/ui/login/log...
chrome/browser/ui/login/login_prompt.cc:127:
url_formatter::FormatUrlForSecurityDisplay(request_url, languages));
Idea: Use FormatUrlForSecurityDisplayOmitScheme iff IsOriginSecure --> true;
otherwise, FormatUrlForSecurityDisplay.

Idea: Always use FormatUrlForSecurityDisplayOmitScheme; if IsOriginSecure -->
false, use an explanation string that says "This web site is not secure" (or
other bikeshedded string).

I don't know if these are good ideas.

chrome/browser/ui/login/login_prompt.cc:131:
l10n_util::GetStringFUTF16(IDS_LOGIN_DIALOG_DESCRIPTION, elided_realm);
As I mentioned on the bug, I really would like to not show the realm at all. I
don't like to display untrustworthy strings in browser chrome, which should
contain only trustworthy/verified information.
