-"

-"   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
