Summary: \letterspacefont and \pdffontexpand, again

Initial Comment:
When expanding a letterspaced font, the base font will
be expanded, too, resulting in the error `font has been
expanded with different parameters' when the base font
is expanded again:

\letterspacefont\lsfont\font 100
\pdffontexpand\lsfont 20 20 5 autoexpand
\pdffontexpand\font   20 20 5 autoexpand
Z\bye

either name is ok with me. We need a new pritimive to load a
new font and expand it, since the current one doesn't load a
new font and hence is making trouble. I would wait for a
while to see how Robert sees it before making any change.

Hello,

I do not think that \pdfexpandfont is a good name for a new 
primitive, as it is too easy to confuse with \pdffontexpand. 
What about \pdfexpandnewfont, as -- if I understand 
correctly -- a new font is loaded?


Jonathan

P.S: Thank you for creating pdfTeX!

Phil Taylor has a suggestion that seems great to me:
introduce a new primitive \pdfexpandfont instead. How do you
see it?

Forget that comment. Of course a change of \pdffontexpand
has to be considered carefully. By you. :-)

No. It's an undocumented primitive. ;-)

sigh. A mistake when implementing the \pdffontexpand
primitive: it should load a new font for expansion, instead
of expanding a loaded font. Too late for change now?
