[Dev-luatex] letterspacing and (no) ligatures

Hi,

here are two bugs:

* in pdftex, \letterspacefont does not disable the ligatures, but this 
is what happens in luatex.

* neither \tagcode nor \pdfnoligatures seem to have any effect (for 
non-letterspaced fonts, that is).

Example:

\input luaotfload.sty
\font\x="Latin Modern Roman:+liga;+tlig" at 12pt
\tagcode\x`\f=-1   % no effect
\pdfnoligatures\x  % ditto
\x fi --

\letterspacefont\y\x 100 % killing the ligatures
\y fi --
\bye

Best regards,
-- 
  Robert
