It adds functionality.  That doesn't make it gratuitous.  One might
just as well call 'POSIX' compatibility gratuitous.  Like it or not,
the GNU utilities represent a de-facto standard that we must conform

Don't be rediculous.  I added 1k of extra space to an existing
utility.  That was part of the calculous in my making the changes I

Or course, we may need to adopt features from bash into our /bin/sh as
time marches forward.

This is no different from what the project has always done.  There's
nothing new that I've done.  Reviewing all the utilities one will find
where people have added features or enhanced compatibility with other
gnu tools.  Don't make me quote all the cvs log entries to prove this
point (but I will if you don't believe me).

Like spitting in the ocean.  There's a bunch of different such tools
and it is a better investment of my time and everybody else's time to
make FreeBSD's find work better in these environments rather than
trying to fix all the places that use it.

I'm also not sure that the maintainers would buy the argument you are
making here.  People outside the BSD community generally use gnu
tools.  The percentage of people using other Unicies is small, and
typically they don't have source to rebuild (Solaris/OpenSolaris is
one exception I can think of).

In short, I'm continuig the long tradition that we've done as FreeBSD
and that BSD and other Unix vendors did before us: compatibility with
other implementations.
