] $WORDCHARS" show?

On the Slackware 9.0.0 host in question:

    bear:~% cat /etc/slackware-version
    Slackware 9.0.0
    bear:~% ~/bin/config.guess
    i686-pc-linux-gnu
    bear:~% 

, the - (minus) does not disappear; I'm left with:

    bear:~% tst -

However, WORDCHARS consists solely of an _ (underscore):

    bear:~% print -r $WORDCHARS
    -
    bear:~% 

When I set WORDCHARS to that which it's set to on another host, my
cygwin host:

    cowberry:~% uname -s
    CYGWIN_NT-5.1
    cowberry:~% print -r $WORDCHARS
    *?_-.[]~=/&;!#$%^(){}<>

, then your requested test only leaves me with "tst ":

    bear:~% WORDCHARS='*?_-.[]~=/&;!#$%^(){}<>'
    bear:~% tst 
                ^---- cursor is here
    bear:~% print -r $WORDCHARS
    *?_-.[]~=/&;!#$%^(){}<>
    bear:~% 

So do I understand correctly that WORDCHARS should be set to more than _
(a lone underscore) in a "zsh -f" shell?

Let me know if you need me to perform any other tests.

[several minutes later]

Ok, I believe I've solved this. My build environment for zsh-4.3.2 was a
zsh-4.2.5 shell with my ~/.{zshenv,zshrc,zlogin} files invoked, which
includes this variable setting: WORDCHARS="_".

When I removed my WORDCHARS setting (and logged out and logged back in),
WORDCHARS reverted to what I presume is the default:

    bear:~% print -r $WORDCHARS
    *?_-.[]~=/&;!#$%^(){}<>
    bear:~% 

I then unpacked zsh-4.3.2.tar.bz into a brand new directory, configured
it, and performed a "make" and a "make check". All the tests in
zsh-4.3.2's "make check" passed.

It doesn't seem right that a "make" or "make check" of a new zsh, if
done from within the environment of an old zsh, should require a
"zsh -f" environment. However, that's your call. It seems to me that if
the Y03 test (or any other test) requires the environment to be set a
certain way, it should set it up itself. My sense here is that the
$WORDCHARS value is presumed set appropriately rather than being set
explicitly.

Thank you for helping me drill down on this problem; I appreciate it
very much.

Eric
