Problem

Completing a long option value written with = loses the option name. For a choice option such as --color, shell completion for --color=a returns auto and always, which can replace the whole current word instead of preserving --color=.

Closes #2847

Reproducer

$ _CLI_COMPLETE=bash_complete COMP_WORDS="cli --color=a" COMP_CWORD=1 cli
# before: plain,auto
# before: plain,always
# expected: plain,--color=auto
# expected: plain,--color=always

Fix

Track the --option= prefix while resolving an incomplete option value, use the value after = for matching, then add the prefix back to plain completion items before shell-specific formatting.

Testing

Added test_long_option_equals_value_completion covering bash, zsh, and PowerShell. Ran:

python -m pytest tests\test_shell_completion.py::test_long_option_equals_value_completion -q
python -m pytest tests\test_shell_completion.py -q
python -m pytest
