Hmmm...   $ find $DIR -print | xargs command

+---------------
| in that case.  In a pinch I would try something like this:
| 
|      $ find $DIR -print | nroff | sed -e 's/  */ /g' | ...

| Since nroff right-justifies by default, we use sed to squeeze multiple

+---------------

The shell (sh, at least) isn't fazed by multiple spaces... at least, not the
AT&T version.  But if you're after efficiency, nroff is the LAST thing you
should use!  ;-)
