描述

Description

Any method to exclude specific files in Stow is only respected if --no-folding is also used. Without --no-folding, Stow may create a symlink for the whole package folder, ignoring the file-level exclusions.

Steps to Reproduce

Create a package folder with some files such that stowing would normally create a folder link (folding).
Create a test file in your package folder, e.g., something.ignore.
Run:
```
stow -R --ignore='\.ignore$' mypackage
```
Observe that something.ignore is still linked.

Now run:

stow --no-folding --ignore='\.ignore$' mypackage

Observe that something.ignore is correctly ignored.

Expected Behavior

The --ignore flag should work regardless of the --no-folding option. Stow should automatically detect that folding isn't possible due to ignored files.

Actual Behavior

Files matching the --ignore pattern are only ignored if --no-folding is used, or if the file layout naturally prevents folding.

Environment

GNU Stow version: 2.4.1
OS: Arch Linux

Notes

This behavior is reproducible with .stow-local-ignore and .stow-global-ignore as well—--no-folding is required for file-level ignores to be respected. This appears to be a bug in how Stow handles folding versus individual file ignores.

研究方向: Investigate how stow handles the ` ignore` flag in relation to folding. Focus on the code that decides whether to create a symlink for the whole directory or individual files. Look for the logic that checks folding conditions and how ignore patterns are applied before folding. The relevant code is likely in the main stow module (e.g., `lib/Stow.pm` or `stow.in`). Consider reading the existing test suite for ignore patterns to understand expected behavior.
