> When reading lines from text files with multiple patterns it is sometimes
> useful to keep track of the file names from which the lines originated.
> Example: read tab-delimited files and map their lines to column headers
> coming from separate files.
> It would be nice to have a {{ReadAllFromTextWithFilename}} transform, which
> modifies {{ReadAllFromText}} transform in a similar way as
> {{ReadFromTextWithFilename}} modifies the {{ReadFromText}} transform to
> produce tuples of file names paired with text lines.
