[tex-live] Ignored italic correction with lua(la)tex format

Hi all,

After a long night of debugging and hair pulling, I finally found why
italic correction for OpenType math fonts is ignored in luatex and
lualatex formats but not in context.

For some reason not yet clear to me, the setting of catcode to 11 in
luatex-unicode-letters.tex causes luatex to not apply italic correction
(might be related to the fact that luatex applies IC selectively).

This minimal example shows the issues:

\input luaotfload.sty
\font\xits={file:xits-math.otf} at 10pt

after commenting the \catcode part in line 18 of
luatex-unicode-letters.tex and rebuilding the format, italic correction
is applied.

I'm not sure what is the proper fix here, though.
