Once the issue that the testsuite harness doesn't set LC_ALL=C like it 
should has been dealt with (I think Mark was working on doing this 
properly, in the .exp files rather than in the Makefile so it works for 
people running runtest manually) so we know that issue doesn't need 
documenting for 4.0, I'll add that documentation, referencing Markus 
Kuhn's page <http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html> as the 
standard description of quoting issues for those not familiar with them.  
(In particular,

#   If you
#   can use only ASCII's typewriter characters, then use the apostrophe
#   character (0x27) as both the left and right quotation mark. If you can
#   use Unicode characters, nice directional quotation marks are available
#   in the form of characters U+2018 and U+2019.

from that page explains the policy used: if you tell GCC that you can use 
Unicode characters by your LC_CTYPE setting, you get the proper quotes, 
otherwise you get neutral vertical quotes.)
