top: allow re-ordering of saved line input upon recall

The original implementation of input line recall keeps
strings in the order established when initially added.
With this commit, that has been changed so any matched
string moves to the top of the saved input line stack.

[ well technically not the top since that's occupied ]
[ by an 'empty' string which serves multiple masters ]

Thus, the most frequently referenced strings over time
will percolate up and remain the most easily recalled.
But just in case anybody prefers the strict historical
ordering, a #define can restore the original behavior.

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