Consider:  During the early stages of porting my software to a new
hostile (i.e. 4BSD) system, I use a shell script named "cc" to get
things compiled right.  No way am I going to edit a zillion Makefiles
to redefine "cc" to "cc.sh", then later change them back.  (Admittedly
augmented "make" provides a way to accomplish this through use of an
environment variable, but the point is that the name of a command
should encode only the command's function, not information about its
type, creator, size, or other irrelevancies.)
