+ Got rid of the spaceflag variable.
+ Make sure that the curline.histnum variable is accurate at the end
  of our history processing, even if we read in some foreign history
  and/or if we replaced the prior line because it was a duplicate of
  the current one.  This enables the history (fc -l) command to work
  properly, even if the current command was HIST_NO_SPACE-ed away.
+ Don't allow remhist() to remove the last line in the history if we
  didn't store the current command.
