keep prefix after glob?

I often use glob to get a list of files. I may loop over this to do similar operations over a file. It'll be nice if I could keep the prefix e.g. (s3://) instead of adding that back in myself:

import s3fs
fs = s3fs.S3FileSystem()

files = fs.glob("s3://bucket/YYYYMM*")
# files = [bucket/path/YYYYMM01, bucket/path/YYYYMM02] ...

Would like

# files = [s3://bucket/path/YYYYMM01, s3://bucket/path/YYYYMM02] ...

Easy to add a user but common enough that it would be nice if I could avoid this step. e.g. have a keep_prefix=True kwarg?

Current work arounds

for file in files:
    pd.read_parquet("s3://" + file)

or

files = ["s3://" + file for file in files]

Start by tracing the s3fs glob implementation used by fs.glob("s3://bucket/YYYYMM*") and check how returned paths are assembled. The change is done when an optional keep_prefix=True form returns paths retaining the s3:// prefix while existing output remains unchanged; add or update focused tests for both forms.
