BTW, is there any reason why history-delete-duplicates
defaults to nil?
I agree it should be t.
I didn't even realize that variable existed when I started this
thread, which is why I asked - why not (always) remove duplicates?
I still wonder what the nil use case is - why would anyone want to
keep duplicates?
See the thread at
http://lists.gnu.org/archive/html/emacs-devel/2004-09/msg00038.html
Thx. The only argument I see in that thread for ever allowing duplicates is
the point RMS raised about a command history. I can see that that might make
some sense in a shell interaction (although there are better ways to see the
shell history with duplicates). I don't see where it makes sense for, say,
the Emacs command history (and certainly not for histories like the
search-ring). But perhaps I'm missing something.
I think that for most uses of a history it makes no sense to keep
duplicates. I'd vote for making the default value be t and letting those few
modes where duplicates might make sense (e.g. shell-mode?) bind it to nil
unless the user has explicitly specified otherwise.
IOW the option values could be:
nil - means never remove duplicates
t (default) - means remove duplicates, but this can be
overridden by a mode (e.g. shell-mode)
non-nil, non-t - means always remove duplicates (never override)
This would require code changes only for those few modes that want to
override the default (t). Plus a change to the defcustom.
