[BUG] glob-style pattern with range ([0-9]) not working

Start with the supplied setuptools-globstyle-bug.zip and the MANIFEST.in rules, then run the documented build and inspect the wheel with unzip -l. Compare global-exclude 202[0-9] with the working 202 and 202[23] patterns. Done means the range pattern excludes file3_20230814T111336.py as expected.

Setup to reproduce the problem

setuptools-globstyle-bug.zip

Description

When MANIFEST.in contains global-exclude *202*, any file with this string is being excluded such as file3_20230814T111336.py (WORKS AS INTENDED).

However, when MANIFEST.in contains global-exclude *202[0-9]*, any file with a string that follows that glob-style pattern gets included, such as one named file3_20230814T111336.py. That is the BUG.

Note that I tested the glob-style pattern an it is valid:

$ find . -name '*202[0-9]*'
./src/file3_20230814T111336.py

Last note, when MANIFEST.in contains global-exclude *202[23]*, that does work and file3_20230814T111336.py gets excluded. The [] syntax seams to work partially, but its "range" functionality does not.

Setuptools is not following what its documentation is referring to at Controlling files in the distribution which points to PyPA’s Packaging User Guide. In this last page, we do find:

matches any one of the characters between the square brackets (which may contain character ranges, e.g., [a-z] or [a-fA-F0-9]).

Expected behavior

global-exclude *202[0-9]*, any file with a string that follows that glob-style pattern should get excluded.

How to Reproduce

setuptools-globstyle-bug.zip provides an environment where one can test this. Simply edit MANIFEST.in to test the glob-style pattern you plan to test and call build to see what gets included in the wheel.

Output

When MANIFEST.in contains global-exclude *202[0-9]*, we notice below that the file file3_20230814T111336.py gets included.
