top: for symmetry with 'E' add 'e' command line switch

Several years after the 'e' & 'E' interactive commands
were introduce to affect memory scaling, an 'E' switch
was added. This was after discovering a dropped Redhat
patch which provided a unique 'M' command line switch.

If only for symmetry it makes sense to offer a similar
command switch ('e') for the Task Area memory scaling.

As was true with 'E', top's help text will show 'e' as
if it were a switch without arguments in order to keep
help text displayed without wrap in an 80x24 terminal.
The man page, however, will show all of the arguments.
