We still support the build down to MSVC 2013, so I think that it is
good to mention the options available for 2013 and 2015 as well, as
noted here:
https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-options/how-to-set-environment-variables-for-the-visual-studio-command-line
"Visual Studio 2015 and earlier versions used VSVARS32.bat, not
VsDevCmd.bat for the same purpose."

Thanks, applied after tweaking the text a bit.  I have applied that
down to 12 where we support MSVC from 2013.
