>Description:
NetBSD is still using an old GPLv2 version of diff. In the meantime,
the other BSDs have developed BSD-licensed replacements and switched
to them. We should investigate porting their code.
>How-To-Repeat:
Type "$ man diff", get directed to info page.
>Fix:
Import diff from FreeBSD/OpenBSD.
