xrootd file globbing only works for some file + object path specifications

[lgray]

uproot version: 5.2.0rc5

dict-style file + object path globbing works fine:

>>> import uproot
>>> events = uproot.dask({"root://cmsdcadisk.fnal.gov//dcache/uscmsdisk/store/data/Run2023C/EGamma0/NANOAOD/PromptNanoAODv11p9_v1-v1/*/*.root":"Events"}, open_files=False)
>>> events.Muon_pt
dask.awkward<Muon-pt, npartitions=71>

however, in-string style does not:

>>> events = uproot.dask("root://cmsdcadisk.fnal.gov//dcache/uscmsdisk/store/data/Run2023C/EGamma0/NANOAOD/PromptNanoAODv11p9_v1-v1/*/*.root:Events", open_files=False)
Traceback (most recent call last):

    files = uproot._util.regularize_files(files, steps_allowed=True, **options)

    'root://cmsdcadisk.fnal.gov//dcache/uscmsdisk/store/data/Run2023C/EGamma0/NANOAOD/PromptNanoAODv11p9_v1-v1/*/*.root:Events'

Files may be specified as:
   * str/bytes: relative or absolute filesystem path or URL, without any colons
         other than Windows drive letter or URL schema.
         Examples: "rel/file.root", "C:\abs\file.root", "http://where/what.root"
   * str/bytes: same with an object-within-ROOT path, separated by a colon.
         Example: "rel/file.root:tdirectory/ttree"
   * pathlib.Path: always interpreted as a filesystem path or URL only (no
         object-within-ROOT path), regardless of whether there are any colons.
         Examples: Path("rel:/file.root"), Path("/abs/path:stuff.root")

Functions that accept many files (uproot.iterate, etc.) also allow:
   * glob syntax in str/bytes and pathlib.Path.
         Examples: Path("rel/*.root"), "/abs/*.root:tdirectory/ttree"
   * dict: keys are filesystem paths, values are objects-within-ROOT paths.
         Example: {"/data_v1/*.root": "ttree_v1", "/data_v2/*.root": "ttree_v2"}
   * already-open TTree objects.
   * iterables of the above.
