Actually, it seems to sort and remove duplicates automatically:

$ _foo () { COMPREPLY=("bar" "foo" "bar" "baz") ; }
$ complete -F _foo foo
$ foo <TAB>
bar  baz  foo  

So that | sort | uniq might not be necessary after all, and by
removing them we could spare two fork()+exec()s.

I'm not sure all supported Bash versions behave this way, though.


Best,
Gábor
