Description

The glob.translate function in Python 3.13 doesn't properly handle path separators when they're included in character ranges. According to the documentation, "wildcards do not match path separators," but this isn't enforced for character ranges that include the path separator.

Expected behavior

Character ranges in glob patterns should not match path separators, consistent with the behavior of single character wildcards (?) and the documented behavior of the module.

Actual behavior

Character ranges that include the path separator (e.g., [%-0] which includes the / character) will match the path separator, contradicting the documented behavior.

Code to reproduce

import glob
import re

# Proper behavior with ? wildcard
r1 = re.compile(glob.translate('a?c', seps=['/']))
print(r1)  # (?s:a[^/]c)\Z
print(r1.match('abc'))  # match object
print(r1.match('a/c'))  # None, correctly doesn't match path separator

# Incorrect behavior with character range
r2 = re.compile(glob.translate('a[%-0]c', seps=['/']))
print(r2)  # (?s:a[%-0]c)\Z
print(r2.match('a0c'))  # match object
print(r2.match('a/c'))  # match object, incorrectly matches path separator

调研方向

从 issue 中的 glob.translate 复现开始,比较 seps=['/'] 时为 ? 和字符范围生成的模式。当字符范围不再匹配路径分隔符,并且文档所述行为已由回归测试覆盖时,即视为完成;请注意,链接的 PR gh-130989 表明相关工作已经在进行中。
