When adding a file that is empty except for a UTF-8 byte order mark to an SVN 
repository, that file gets assigned an svn:mime-type property of 
application/octet-stream even though it is clearly meant to be a text file. 
This is a problem because some text editors use the UTF-8 byte order mark to 
identify the encoding of a file and thus automatically add that mark even to 
empty files.

An exemplary tool combination causing this problem to appear is that of 
Microsoft Visual Studio with the VisualSVN add-in because when Visual Studio 
creates an empty code file, VisualSVN will automatically add this file to SVN 
and the code file will thus be identified as a binary file.

The reason for this issue is that the svn_io_detect_mimetype2 (and 
svn_io_is_binary_data) functions have no specific support for detecting the UTF-
8 byte order mark.

The solution discussed on the mailing list would be to patch one of these 
functions so that the byte order mark is not interpreted as binary data.
