What a pity ! But even the ASCII display "|-" for \vdash, and "|="
for \models would be better than just the name of the symbol (I think
it is the same for many of the other symbols). As I am working on type
systems, my articles are full type inference rules with lots of
\vdashes. Therefore *for the kind of document I write* LyX has little
advantages over emacs+LaTeX if I cannot have \vdash displayed
graphically "|-".
