Fixes #12726.

Summary

Wrapping a %run argument in single or double quotes now suppresses shell-style glob expansion of that argument matching how real shels behave. the existing backslash-escape (\*) and -G flag are unchanged. Before this with foo.txt and bar.txt in the working directory:

In [1]: %run script.py "*.txt"
# sys.argv -> ['foo.txt', 'bar.txt']

After:

In [1]: %run script.py "*.txt"
# sys.argv -> ['*.txt']

Motivation

The issue thread already has a maintainer pointer:

Looks like an oversight in IPython.core.magics.execution.ExecutionMagics.parse_options.

What changed

I added a new helper arg_split_with_quotes(commandline, strict=True) in IPython/utils/_process_common.py (re-exported from IPython.utils.process). Returns [(token, was_quoted), ...]. shlex-based on two passes - posix=True and posix=False - so the quote semantics are the same on every platform

%run consults it after parse_options and skips globbing for any arg_lst entry that came from a quoted token in parameter_s. Docstring updated.

This is a small backwards-incompatible behavior change so ofc anyone depending on the previous "quotes do not suppress globs" behavior wouldd see different output. I added docs/source/whatsnew/pr/incompat-run-quoted-glob.rst.

Tests

• tests/test_process.py: parametrized unit tests for arg_split_with_quotes covering bare, double-quoted, single-quoted, mixed-with-options and strict=False cases.
• tests/test_run.py: new integration test test_run_quoted_glob_arg_is_not_expanded that runs %run -i against a small script in a tempdir with f les that would match *.txt, and checks sys.argv for bare double-quoted and (POSIX-only) single-quoted forms.
• Updated doctest_run_option_parser_for_posix its expected output was locking in the old buggy behavior.

Local run on Windows / Python 3.13:

pytest tests/test_run.py tests/test_process.py tests/test_path.py
=> 62 passed, 12 skipped

The POSIX-only single-quote doctest is done by CI on the Linux/macOS jobs.

Open questions

• The Windows doctest doctest_run_option_parser_for_windows still describes the existing 'print*.py' → ["'print*.py'"] behavior. That case is preserved by the patch (CommandLineToArgvW keeps the literal single quotes so they never enter the quoted_remaining set) so I left it.
• Single quotes on Windows stay documented as unsupported.
