⚡️ Speed up function _resolve_incomplete by 59%

[codeflash-ai]

📄 59% (0.59x) speedup for _resolve_incomplete in src/click/shell_completion.py

⏱️ Runtime : 325 microseconds → 204 microseconds (best of 5 runs)

📝 Explanation and details

To optimize the performance of the given code, we can reduce redundant checks and improve the structure for better efficiency. Here's a revised version.

Optimizations made.

1. Combine Conditions: Combined checks for incomplete == "=" and incomplete containing = with the _start_of_option check to reduce nested conditional checks.
2. Early Return: Eliminated unnecessary iteration by checking the conditions early and returning immediately when applicable.
3. Reduced Redundancy: Avoided re-checking the same conditions, especially for the incomplete argument and processed parameters.

This should result in more efficient execution by reducing the number of checks and iterations the program performs.
