+In its basic form this command prints one or more blank lines. However if
+you pass it a string it will replicate the string for the width of the 
+screen (default 80) and then print that one or more times, so:
+
+  blank 2
+
+prints two blank lines
+
+  blank - 
+
+prints a row of - characters once.
+
+  blank abc
+
+prints 'abcabcabcabcabcabc....'

+This is really only of any use in a script file and you can print a maximum
+of 9 lines.
