bug in vared with command history

bug in vared with command history

[Greg Klanderman]

(I sent this a few weeks ago and about a week later got a bounce
saying it was undeliverable so I am trying it again.  Please copy me
in any replies.)



In zsh 3.1.5,

% foo=bar
% fc -R <(echo one ; echo two) ; vared -h -p "> " foo

The inital contents is "bar".
Hit up-arrow once and you have "one", not "two".
Once the command completes, you can see that "two" has 
made it into the history.

I assume it is preventing you from getting at the last
command because that's usually the one you're executing.
But I'd like to be able to do something like:

    while cmd="" && vared -h -p "> " cmd ; do
      # process $cmd
      fc -R <(echo "$cmd")
    done

which works great except that I can never get to the very 
last command in the history.

thanks,
Greg

This has already been changed to work the way you want, in 3.1.6-dev-17.

Ha!!  I started using zsh about a year ago (3.1.4) and I have to say
it has been the most reliable free software I've ever used... let
alone for a BETA.  By comparison, when I decided to switch to a Bourne 
style shell from tcsh, I first went to BASH (2.02) which is supposed
to be a stable release.  Within about 2 days I'd found at least ten
ways to crash it hard, was disgusted, and switched to zsh at the
recommendation of a few xemacs-beta list members.  It's the only
worthy shell in MHO.

Keep up the excellent work!
