`compgen' only generates possible completions.  It's readline's job to
display them and append the appropriate characters.  You tell readline
how to behave when you install the completion with `complete'.  For
instance, `complete -o filenames ...' will tell readline that the
completion spec generates filenames, so the resulting words should be
quoted, if necessary, checked whether they are directories, and so on.

If you want to change these options on the fly, while a completion
function is executing, you can use `compopt' to set or unset them.
