while the current erasedups logic is implemented in bash, I want this
also get into bash,
we may define another control like "erasedupsinfile" if the user set
that we will erase dups in history file as well

HISTCONTROL=ignorespace:ignoredups:erasedups:erasedupsinfile


if we contribute a binary to dedup in history file, we still need the
logic to call it automatically, depending some similar control
variable is set
