Actually, `vared' completes its line in the same way a command line is
completed. I.e. it uses all the `compctl' definitions you have
(including the one for `-C' for the first word on the line).
What Bart probably meant was that with the new completion system in
version 3.1.6 you can set the parameter `compcontext' in such a
function to specify how words in the line read should be completed.
Since you seem to use an older version: if your version already
supports the `-T' flag to `compctl' (which is quite old), you can use
that to say what should be completed in such a function, e.g.:
compctl -Tk '(foo bar baz)'
compctl -T ... # reset to standard value
Resetting it should be possible by first storing the output of
`compctl -LT' and later `eval'ing it (be careful if that contains
If you are using a 3.1.6, you'll have to add a `-tn' to the first
`compctl -T'. But then... if you are using 3.1.6, you probably should
think about moving to the function based completion system anyway.
