Standards don't conform to itself (quoting)!

[Askar Safin]

Hi. The standards recommend using 'such' and "such" over `such' quotes in ASCII 
text.
And I absolutely agree with them, `such' quotes are really ugly.
Unfortunately, the standards violate itself and use `such wrong quotes' in some 
places.
So, I propose this patch. The patch is to make-stds.texi file, so GNU Make 
should be updated as well.
