Unless you need an overall total for all files (as opposed to the per
file count request) this shouldn't break at all.  xargs will chunk the
file list out of find into smaller pieces to avoid overflowing command
line arguments to wc.  Thus, for long lists you'll execute wc more
than once, so you'll end up with more than one set of final totals.

(Or you could use "-l 1" with xargs and it'll run wc for each file so
you'll never see total lines :-))
