geotifcp Warning: Unknown field (TIFFTAG)

Description
When using geotifcp, 'unknown' TIFFTAGS are being removed with a warning:
GDAL_METADATA: TIFFReadDirectory: Warning, Unknown field with tag 42112 (0xa480) encountered. GDAL_NODATA: TIFFReadDirectory: Warning, Unknown field with tag 42113 (0xa481) encountered.
It would be better if the 'unknown' TIFFTAGS are collected and passed on, since some 'unknown' TIFFTAGS are in reality very well known (such as GDAL_NODATA) with software relying on the existence of this TIFFTAG to render properly.
As a general rule, the assumption should be: if the TIFFTAG exists, it exists for a reason and should not be discarded because it is not on a list that (I believe) is not being actively maintained.
