Hi,

I installed zsh 3.0.5 today and immediately liked it a lot better than
bash2, which I'd previously been using. The only zsh feature I dislike
is the csh-style completion (TAB to complete the unambiguous prefix,
^D to list possible completions), so I hacked zsh to provide
bash-style completion (TAB completes the unambiguous prefix, TAB again
lists possible completions). Patches against 3.0.5 are attached. Hope
they can be of use.

The patches also fix a minor bug (lastambig was not being reset when
the completion list is invalidated).

To use bash-style completion, just bind your favorite key to
'complete-or-list'. I use 'bindkey \\t complete-or-list'.

OBTW, I put completeorlist() at the end of zle_tricky.c because it
uses lastambig. There's probably a cleaner way, e.g. defining
COMP_COMPLETE_OR_LIST and doing the dirty work (all four lines of it)
within do_complete().

Oh, and I'm not on the list, so please Cc: me any questions or
comments.

DES
