+"
+" git diff myfile
+"
+" * Unsaved: the buffer contents is not the same as the file on disk so we
+" need to pass two instances of the file to git-diff:

+" git diff myfileA myfileB

+" git-diff on stdin via the second argument to vim's system() function.
+" Unfortunately git-diff does not do CRLF conversion for input received on
+" stdin, and git-show never performs CRLF conversion, so repos with CRLF
+" conversion report that every line is modified due to mismatching EOLs.
+"
+" Instead, we write the buffer contents to a temporary file - myfileB in this
+" example. Note the file extension must be preserved for the CRLF
+" conversion to work.
+"
+" Before diffing a buffer for the first time, we check whether git knows about
+" the file:
+"
+" git ls-files --error-unmatch myfile
+"
+" After running the diff we pass it through grep where available to reduce
+" subsequent processing by the plugin. If grep is not available the plugin
