Works for me on the Emacs 24 branch:

`M-x eww RET file:///tmp/cert.html RET'

I get the error ⌜This function requires Emacs to be compiled with libxml2⌝.

IOW, I can't read.

In my defense, ⌜/home/test/test.html⌝ produced the error ⌜/80 Name or service not known⌝, and ⌜file://home/test/test.html⌝ produced an FTP buffer with the error ⌜home: No address associated with hostname⌝, so by the time I tried ⌜file:///home/test/test.html⌝ and the debugger popped up yet again, I assumed the error was just another complaint about my syntax.

Sorry for the mistaken bug report.

	This could probably be improved, – either the error message, or
	the treatment of URIs which look like (absolute?) filenames.

	Indeed, a file://home/ URI means “get files from the host named
	‘home’.”  Cf.: file:/home/, which means “a directory named
	/home/ on the local filesystem.”

	ACK, closing.

Nobody can ever remember the syntax of a file: URI, though, so I think
`M-x eww' should DWIM it a bit.

If the URL is "/some/file/that/exists" or starts with "file:" and you
can then make (sort of) sense of it, then `M-x eww' should load that
file.

What about "d:/some/file/that/exists" on Windows?

Sure, that too.  The DWIM code should call `file-exists-p' a bit on
strings that look like they could possibly be files.

	Like, perhaps, the strings matching "^\\([a-z]:\\)?/"?

Yeah, perhaps.  Does have a "does this string look like a file name if
you squint at it?" function?

Beware: file-exists-p calls file handlers, and can return non-nil for
remote files.  Not sure you want that here.

Hm...  I think that would usually be fine?  If it's a file accessible
via Tramp (for instance), I think the user would normally want eww to
display it.

Usually, it is the other way around: if `url-handler-mode' is enabled,
one shall be able to open a URL like "ssh://user@host/path/to/file".

Hmm, doesn't seem to work just now. Need to debug.

Best regards, Michael.
