It handles filenames with spaces, but it will fall over if you
encounter files with newlines (for example).  The link you
posted has a large number of comments about this issue, with a
lot of misunderstanding going on.  There are good reasons to use
the ``while read ...`` trick, but for full robustness you have
to know that your filenames are "well behaved" (i.e., they don't
have "weird" characters in them).

I generally prefer the ``find ... -print0 | xargs -0`` idiom
posted elsewhere in this thread, especially if I'm already using
``find``, as all possible weird characters are handled properly.
