Subject: bug#17417: 24.3.90; EWW on MS-Windows tries to connect imaginary FTP server when viewing "file://" URLs
Date: Tue, 06 May 2014 10:55:46 +0300

On MS-Windows, in your Web browser, visit this page (as an example;
other pages exhibit similar behavior):

  http://www.unicode.org/standard/standard.html

Save it to your disk as, say 'D:/foo/bar/Unicode Standard.html'.

Then visit the file in Emacs's eww like this:

 emacs -Q
 M-x eww RET file:///D:/foo/bar/Unicode Standard.html RET

The page is displayed, but Emacs also says

  Opening FTP connection to d...

Also, a buffer named *ftp anonymous <at> d* pops up showing this:

  Invalid help command foo.
  open d
  Unknown host d.

This does not happen when visiting the same page via http://.  I suspect
that the "D:" part of the URL fools eww or some function it calls to
perceive the URL as an FTP address, or something.

Btw, I also see this message in *Messages*, not sure if it's related:

  Blocking call to accept-process-output with quit inhibited!!
