Jim Warner 2efe275512 top: enable recall of previous input lines for re-edit 
With this commit, users can now retrieve previous line
input for re-editing and/or re-input using the Up/Down
arrow keys (or their aliases). This mirrors the 'bash'
or 'less' interface and represents a major enhancement
achieved via a somewhat minor impact to our code base.

[ 33 lines of code, 5 closing braces & some comments ]
[ all in 1 function, when TERMIOS_ONLY isn't defined ]

Currently, the upper limit for such recallable strings
has been set at 50 but that could be easily increased.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
