I don't know how you gather this when Richard directly replied to the
posting of yours
Message-ID: <address@hidden>
containing the proposal:
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.
