Summary: Amount of extra kerning is wrong/has changed

Initial Comment:
With \kn[ab]ccode=1000 a kern of 1em should be inserted.
(Here, it's 2.32pt:)

\tracingoutput1
\showboxdepth\maxdimen
\showboxbreadth\maxdimen
\pdfappendkern1 \pdfprependkern1
\knaccode\font`y=1000
\knbccode\font`y=1000

This bug is caused by missing of declaration of k inside the
function get_auto_kern, hence the global variable k is taken
with wrong type (eight_bits).

In fact, the kerning amount wraps at a kerning code of 256:

\tracingoutput1
\showboxbreadth\maxdimen
\pdfappendkern1
\knaccode\font`y=255 y % 2.55pt
\knaccode\font`y=257 y % 0.01pt
\knaccode\font`y=513 y % 0.01pt
\bye
