I used a newline since the original listing comes from `find'.

Yes, that could be the case.

That works, thanks! However, I also want files from sub folders to be
found, so I use `find' to list them.

Here is my latest attempt, using the idea of setting IFS to `:':

_mm2() {
    local cur files
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    files=$(find /home/mathias/Videos/movies/ -iname '*.avi' -type f -
printf "%p:")
    OLDIFS=$IFS
    IFS=:
    COMPREPLY=($(compgen -W "${files}" -- ${cur}))
    IFS=$OLDIFS
}
complete -o filenames -F _mm2 mm

Looks like it should work but it does not. Typing mm<SPC><TAB> gives
the listing and completes all the way to the path, but if I add B
again it does not match Brazil.

Any ideas?
