Adjust matched file list
If we pass a directory to commit whose only committable files
are largefiles, the core commit code aborts before finding
the largefiles.
So we do the following:

we explicitly add the largefiles to the match list and remove
the directory.
In other cases, we leave the match list unmodified.
