i'm actually a relatively old whippersnapper as these things go: my
first UNIX was some internal bell labs predecessor to System III,
ca. 1979. and yes -- i've certainly hit such limits in the past,
and embraced xargs with a vengeance as a result.
but now isn't then. it's too bad we can't make rmmproc work as well
as a modern rm. but having just browsed the mh sources a bit, i
begin to see the problem. as always. :-)
