Public bug reported:
After upgrading to wily, trying to Tab autocomplete prints a bunch of
errors.
It seems that
if [[ -z "$skip_global_compinit" ]]; then
autoload -U compinit
compinit
fi
in /etc/zsh/zshrc, and the completion rules it loads from
/usr/share/zsh/functions/Completion, is incompatible with KSH_ARRAYS and
KSH_GLOB, which previously worked fine in vivid.
Repro:
---
sudo useradd -m zshtest
sudo su - zshtest
cat >.zshrc <<EOF
emulate sh
setopt KSH_ARRAYS
setopt KSH_GLOB
EOF
sudo su - zshtest
cd /<TAB>

Putting skip_global_compinit=1 in ~/.zshenv works around the problem, as
does "unsetopt GLOBAL_RCS".
I imagine my set up is unsupported, but I notice that
/usr/share/zsh/functions/Completion/compinit at least makes an attempt to avoid
this by doing
---
emulate -L zsh
setopt extendedglob

One pattern that seems likely to be problematic is the dynamic
definition of functions inside other functions, such as _next_tags
creating _all_labels inside its body, which presumably uses the current
shell options rather than the ones the completions assume are active.
