Re: How to avoid a "basic" single quote being replaced by a "curvy" one?

You're looking in the right place.  They're not in the manual because
these changes are post-5.2.  here's what in the development manual.
(alternatively, you could use the 5.2 texinfo.tex and then wouldn't need
the @tex settings.  i believe.)

sorry for all the continuing complications.

File: texinfo.info,  Node: PDF Colors

8.9.4 PDF Colors
----------------

By default, urls and cross-reference links are printed in black in PDF
output.  Very occasionally, however, you may want to highlight such
"live" links with a different color, as is commonly done on web pages.
Texinfo provides a PDF-specific option for specifying these colors,
which must be used inside '@tex':

     @tex
     \global\def\linkcolor{1 0 0}  % red
     \global\def\urlcolor{0 1 0}   % green
     @end tex

  '\urlcolor' changes the color of '@url' output (both the actual url
and any textual label), while '\linkcolor' changes the color for
cross-references to nodes, etc.  They are independent.

  The three given values must be numbers between 0 and 1, specifying the
amount of red, green, and blue respectively.

  These definitions only have an effect when the PDF output is produced
with the pdfTeX program, not with other ways of getting from Texinfo to
PDF (e.g., TeX to DVI to PDF). Consequently, it is ok to specify this
option unconditionally within '@tex', as shown above.  It is ignored
when DVI is being produced.

  We do not recommend colorizing just for fun; unless you have a
specific reason to use colors, best to skip it.
