Re: [PATCH] gitweb: Support comparing blobs (files) with different names

As to browsers: Mozilla 1.7.12 implements RFC2183 correctly, although for
example shows %0A / \n as a strange symbol in "save as" dialog, created
file has embedded newline in filename, as it should. But both Lynx 2.8.5,
and ELinks 0.10.3 do not implement it fully and without errors.

So that is why we have:

	# It not worth potential problems to try to carry newlines
	# in the header; it is just _suggested_ filename
	$filename =~ s/[[:cntrl:]\n\r]/_/g;

I think the logic in the comment is very sane, although I am not
sure if saying \n \r when you say :cntrl: is necessary.
