The fact that you need a paragraph this long to describe how to avoid some
of the confusion when using rsync pretty much speaks for itself.  Rsync
definitely has its own syntax and is much more sensitive than other unix
tools, so it's not unwarranted that people might be confused.  I don't know
anyone who fully understands the include/exclude filters either, at least
not without rereading the man page a few times.
