TIOCSTI t_lnextc: safe?

[der Mouse]

I have a program that sometimes wants to use TIOCSTI to stuff back the
literal-next character, to quote the next character the user types.

This works fine on real BSD.  However, when I try the same program on
Suns, it sometimes works (release 3.5) and sometimes doesn't (release
4.0.3).  When it fails, the TIOCSTI results in the literal-next
character itself being read, rather than the next character the user
types.  (As if the lnextc quoted itself when TIOCSTIed.)

What I want to know is, am I wrong in expecting this to work?  In other
words, is the misbehavior under Sun release 4.0.3 a Sun bug or me
expecting too much?

(If anyone knows of a simple fix, I'd love to hear about it.)
