zsh completion emits ANSI color codes when FORCE_COLOR=1 is set

[troykirin]

When FORCE_COLOR=1 is set in the environment (common for users who want colored output from CLI tools), the zsh completion for task emits raw ANSI escape codes instead of clean task names.

Steps to reproduce

export FORCE_COLOR=1
task <Tab>

Expected behavior

Clean completion list of task names

Actual behavior

Completion shows literal escape codes like $'\033'\[

Environment

• task version: 3.45.4
• Shell: zsh 5.9
• OS: macOS 14.x (Darwin)

Root cause

The __task_list() function in task --completion zsh runs task --list-all which respects FORCE_COLOR and emits colored output. The ANSI codes then leak into zsh's completion system.

Suggested fix

The completion script should either:

1. Pass --color=false when calling task for completion, or
2. Wrap the call with NO_COLOR=1 / FORCE_COLOR=

Current workaround

Override __task_list() after compinit to use:

cmd=(env FORCE_COLOR= CLICOLOR_FORCE= NO_COLOR=1 task --color=false)

@troykirin could you set envar GO_TASK_COMPLETION_LIST_OPTION to GO_TASK_COMPLETION_LIST_OPTION=--color=false --list-all and see if that also works. That could be a better way to solve it.

@troykirin you will probably need to set the envar as suggested. However, there is also a small odd behaviour which PR #2584 would address.

GO_TASK_COMPLETION_LIST_OPTION=--color=false --list-all
