Exception with EXTMATCH on pattern like '!(not)_@(this|that)'

* **OS:** Arch Linux * **python version:** 3.12.3 * **wcmatch version:** 8.5.1 When using a pattern like `!(not)_@(this|that)` and EXTMATCH an exception `missing ), unterminated subpattern at position 5` is raised. The issue happens when a `!(pattern-list)` is followed by a `@(pattern-list)`. As a trivialized example say I have the files `1_foo`, `2_foo` and `3_bar` and I want to match all files except the 2nd, I could use a pattern `!(2)_@(foo|bar)`. Matching the 1st file like this: ```python from wcmatch import fnmatch fnmatch.fnmatch('1_foo', '!(2)_@(foo|bar)', flags = fnmatch.EXTMATCH) ``` Should result `True` but instead the fnmatch call raises this exception: ```python Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.12/site-packages/wcmatch/fnmatch.py", line 86, in fnmatch return bool(_wcparse.compile(patterns, flags, limit, exclude=exclude).match(filename)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/wcmatch/_wcparse.py", line 787, in compile positive, negative = compile_pattern(patterns, flags, limit, exclude) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/wcmatch/_wcparse.py", line 739, in compile_pattern positive.append(_compile(expanded, flags)) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/wcmatch/_wcparse.py", line 798, in _compile return re.compile(WcParse(pattern, flags & FLAG_MASK).parse()) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/__init__.py", line 228, in compile return _compile(pattern, flags) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/__init__.py", line 307, in _compile p = _compiler.compile(pattern, flags) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_compiler.py", line 745, in compile p = _parser.parse(p, flags) ^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_parser.py", line 979, in parse p = _parse_sub(source, state, flags & SRE_FLAG_VERBOSE, 0) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_parser.py", line 460, in _parse_sub itemsappend(_parse(source, state, verbose, nested + 1, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_parser.py", line 862, in _parse p = _parse_sub(source, state, sub_verbose, nested + 1) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_parser.py", line 460, in _parse_sub itemsappend(_parse(source, state, verbose, nested + 1, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/re/_parser.py", line 864, in _parse raise source.error("missing ), unterminated subpattern", re.error: missing ), unterminated subpattern at position 5 ``` In bash it works: ```bash $ touch 1_foo 2_foo 3_bar $ ls !(2)_@(foo|bar) 1_foo 3_bar ```
