TERM problem under OSF

TERM problem under OSF

[Vincent Lefevre]

It seems that zsh takes the wrong terminfo data under OSF:

greux:~> rl lepois                                                    <13:20:06

Setting TERM=$TERM after TERMINFO is changed should solve the problem,
but why doesn't zsh detect when TERMINFO is changed?

It doesn't know anything about curses, nor termcap, and there are a whole
load of different implementations which might be linked in, as we've been
seeing recently.  So there's no simple way of knowing whether TERMINFO is
relevant at all.

I suppose there's nothing to stop us doing some more
implementation-specific probing, now we have separate termcap and terminfo
modules, and shovelling some extra code into those, linking in the
appropriate version when necessary (echotc and echoti already depend on the
respective modules).

Even when zsh is compiled with --with-curses-terminfo?

That just changes the order in which the curses and termcap libraries are
searched for to prefer curses.  The code still uses plain old termcap
calls, as it always has.  It still doesn't know anything about the
underlying library.
