When rc scans the line
echo $a*
the star is part of the variable name, so 'a*' is looked up and
printed out, for example
; 'a*' = fu
; echo $a*
; fu
However, when rc scans the line
echo $a ^ *
it finds (well, sometimes) a to be the empty string, concatinates that
with * and then globs that string. This string is just '*' so printing
out all the files in the directory is what rc should do.
