Subject: glomming and variable woerdness

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.
