Well, there's no harm in being explicit (this patch is a
replacement).

The exit trap isn't run before an exec, for just the same reason that
.zlogout isn't, i.e. the shell isn't exiting, it's overlaying a
process without forking first.  I should think the only thing you can
do is hook into exec itself by an alias or function.  But the securer
you want to be, the better it probably is just to call whatever
explicitly before the exec.  Unless you're saying something slightly
different to what I've understood.

 If tt(ZDOTDIR) is unset, tt(HOME) is used instead.
 Those files listed above as being in tt(/etc) may be in another
 directory, depending on the installation.
