patch 9.0.1972: win32: missing '**' expansion test Commit: https://github.com/vim/vim/commit/4a1ad5556423dca5f5b7ee39f143579e67569ae1 Author: Ken Takata <kentkt@csc.jp> Date: Mon Oct 2 21:31:31 2023 +0200 patch 9.0.1972: win32: missing '**' expansion test Problem: win32: missing '**' expansion test (after v9.0.1947) Solution: Add test for MS-Windows win32: Add "**" test Vim supports "**" on MS-Windows. However, it is not tested by `Test_glob_extended_bash`. Unlike Unix, it doesn't use 'shell' and doesn't support {,} expansion. So, I added as a separate test. related: #13205 closes: #13250 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Ken Takata <kentkt@csc.jp>
