This is already handled by @
But calling pdftex -ini xx.tex on this file

\showthe\pdfimageresolution
\showthe\pdfoptionpdfminorversion
\end

gives:

(./xx.tex

0.
l.1 \showthe\pdfimageresolution

0.
l.2 \showthe\pdfoptionpdfminorversion
So the user has to know that "0" means "72 dpi". With the patch below,
already the call to barebones pdftex -ini xx.tex gives:

(./xx.tex
...
72.
l.1 \showthe\pdfimageresolution
?
...
4.
l.2 \showthe\pdfoptionpdfminorversion
And if i set this to 3 in pdftexconfig.tex, after a texconfig init run i
get by calling pdftex xx.tex (not in ini mode):
...
3.
l.2 \showthe\pdfoptionpdfminorversion
Unclear how large parts of

@p procedure check_and_set_pdfoptionpdfminorversion;

are then obsolete by this patch. And yes, it should go into pdftex.ch (i
only use tex.ch2 for testing).
