The version with xargs is much better: it runs a single instance of
chmod with all the files (or as many as will fit) as arguments, rather
than running a separate instance of chmod for every file.
The downside is that you can only use xargs this way for programs that
let you specify an arbitrary number of filenames lasting up to the end
of the command line. Fortunately, most command-line Unix utilities
behave this way or can be made to behave this way.
