Hello. I'm not a subscriber of this list, but I found a weirdness
while using zsh-2.6-beta8 and 10, so I'll report it here.
After I replaced my zsh from 2.5 to 2.6beta, I found that saved
history was not read correctly.
Finally I found that when I use $(non-zsh-builtin-command), the
content of $HISTFILE is changed (just like when an interactive shell
exits). I believe there are something wrong with command
substitution... I have never encountered such a problem with zsh 2.5.
Please send me responses (if any). Thank you.

I send a `fix' for that in article 337 some time ago, I send it again as noone
responded. It fixes the problem but is completely disables saving history on
exec since an other bug I'm not going to fix (I have no time and I do not know
exec.c well enough).

Subject: HISTORY saving fixes
To: zsh-workers@math.gatech.edu (zsh-workers)
Zsh saves history on each command substitution. I thought that this bug was
corrected long ago.
The patch below fixes this, and it also saves history when a builtin is
exec'ed. It also disables history saving on exec in the startup files
(that's what Mark Borges complaind about a lot). That's because zsh loads
the history file only after processing the startup files so saving it with
append_history unset would wipe out the history. History saving is also
disabled in zexit for the same reason.
Unfortunately the exec part of this fix does not work as expected. After
this patch zsh will never save anything on exec. That is because subsh is
always true since entersubsh is called from exec.c near line 1241 for each
command or builtin executed with exec. This seems illogical for me but I do
not understand these things completely so I'd leave the fix to someone else.
The patch is for vanilla beta10. For hzoli10.x the first hunk fails but it
can be merged easily by hand, and the really important part is the second
hunk.

Sorry, I meant to have a look at this but I've been busy too.
If you apply this after Zoltan's patch, it should restore the expected
behaviour. It simply changes the flag for subshells (subsh) in the
case where it's not a true subshell but an exec about to happen. I
can't see a problem with this and the obvious tests seem to work.
