Changed method to limit the number of History entries loaded

Browse Source 
The previous code limited the number of entries that were read into
the history array, but the user is expecting a maximum on the
number of entries displayed. This can make a little difference in
two cases:
 - if there are duplicate entries (dups are checked for and removed)
 - if some entries are not strings (unlikely, but not impossible)

The new code just stops adding history entries when the user
specified count is reached.
