This makes me want to get approval on a better version of my history-
rewriting patch and get it into 4.2.5.  If some folks would take a look
at this and let me know: (1) do you like the patch for 4.3.0? and (2) do
you like the idea of putting it into 4.2.5 as well.

This patch adds the option HIST_OVERWRITE that is off by default.  This
changes the default history-rewriting strategy to one that uses the name
$HISTFILE.new for writing out the history lines, and then renaming it
over $HISTFILE when it is done (both actions happen with the history
file locked).  If the user chooses to set the HIST_OVERWRITE option, zsh
goes back to the current algorithm of directly re-writing the history
lines to the history file (also while locked).

The reason I chose to change the default is that it is safer to not
truncate the history file when rewriting it.
