Well, yes, for the most part. I guess I'm just showing my age, unix-wise.
Back in the good old days with the standard Bourne shell, globbing didn't
quite work like the present. Plus, * by itself means a lot of things to
the shells. Evaling the results of the 'echo -n' and '-n' by itself may
have different results, if a file was created with the name '-n'.

Habit, I guess. After all these years, that sequence just flows off
my fingertips...
