This is strictly a nit, so please don't take offense.  The advice you give
is right on; the example is slightly off.

csh (and tcsh I presume) implement a bunch of frequently-used commands like
ls, rm, cd, etc. directly for improved performance.  Once in a while this
can cause confusion since the built-in version may not always have the same
default behavior as the versions in /bin (or /usr/bin, whatever).
