Xcode: Example install of language specification for Xcode 4.x.

Browse source 
go.xclangspec is identical to the one in misc/xcode/3/, except for the heading.

Partial workaround for issue 2401.

go.xclangspec
Go language specification for Xcode 4.x.
This is a preliminary version that supports basic syntax coloring
(such as keywords, literals, and comments) and an attempt to provide
some structure information (incomplete).
There is not much documentation available regarding the format
of .xclangspec files. As a starting point, see for instance the
outdated documentation at:
http://maxao.free.fr/xcode-plugin-interface/specifications.html
