This default mapping is provided as a convenience only. Users can edit 
.gitattributes as needed. If we assume that the number of Macintosh and 
iOS (iPhone, iPad, iPod Touch) programmers heavily outweighs the number 
of Matlab users, then the convenience of having .m in the default list 
may be justified.

It also is reasonable to ask if the "*.m diff=objc" mapping actually 
produces an inferior diff hunk-header[1] for Matlab files than when 
"diff=objc" is not present.
