wherein it says: -strip will remove all EXIF data as well as the thumbnail.

What I mean is that there should be a way to just be able to remove a
thumbnail, without hurting the rest of the EXIF data. The mighty
imagemagick should be able to do that.

Or at least on the man page at -strip, say to try jhead(1) if one wants
to do that.
