If we could find which font they are coming from then we could use the 
same one.

Running "latex" to produce a dvi and looking at the contents of the dvi
(I don't know if there's a better way of doing this)
it appears to be a font "ectt1000".  This appears to be a "European 
Computer Modern" font.  Examining that font, opening and closing double 
quotes are at positions hex 10 and 11.

The example below shows that it will be possible to access these glyphs 
from within texinfo.tex.

\input texinfo

@catcode`@"=12@relax
@font@quotefont=ectt1000
{
@quotefont
XXX

@char"10 x@char"11

XXX
}

@bye

It would take some work to only load this font on demand if these 
characters are demanded in a fixed-width environment, and to check the 
font size is always correct in different contexts and so on.

May I ask why you want to use these characters?  I imagine that code 
samples would rarely need directional quotes.
