Yes, the proposed BaseTools script is working for:
MdeModulePkg/*Ufs*/

to match changes made in both directories.

I am also fine (and prefer) for the wildcard character to match multiple
levels of folders.

The script is working like the 2nd option, and I think it is expected.
So, there seems to me no bug in my tests.


I do met a little problem that for a patch that touches multiple features,
the contacts order in the output is not ideally perfect:

Content in Maintainers.txt:
'''
MdeModulePkg
F: MdeModulePkg/
W: https://github.com/tianocore/tianocore.github.io/wiki/MdeModulePkg
M: Jian J Wang <jian.j.wang at intel.com>
M: Hao A Wu <hao.a.wu at intel.com>

F: MdeModulePkg/*Ufs*/
R: Ufs Guy <ufs at test.com>

F: MdeModulePkg/Include/*Hii*.h
F: MdeModulePkg/*Hii*/
R: Hii Guy <hii at test.com>
'''

Script output:
'''
$ py BaseTools/Scripts/GetMaintainer.py HEAD
MdeModulePkg/Bus/Pci/UfsPciHcDxe/UfsPciHcDxe.inf
MdeModulePkg/Universal/HiiDatabaseDxe/HiiDatabase.uni
  Jian J Wang <jian.j.wang at intel.com>
  Hao A Wu <hao.a.wu at intel.com>
  Ufs Guy <ufs at test.com>
  devel at edk2.groups.io
  Hii Guy <hii at test.com>
'''

The 'Hii Guy' is at the end of the list.

But this is a rather minor problem and does not impact the use at all.

Best Regards,
Hao Wu
