See the following reproduce example:

$ cat ssh_compspec
COMP_WORDBREAKS=${COMP_WORDBREAKS//[=:]/}

function _ssh()
{
     local cur="$2" pre="$3"
     local options=(
         ProxyCommand='/usr/bin/nc -x host:port %h %p -X 5'
         ProxyCommand='/usr/bin/nc -x host:port %h %p -X connect'
         ConnectTimeout=10 )
     local i saveIFS="$IFS"

     if [[ $pre == '-o' ]]; then
         for ((i=0; i < ${#options[@]}; ++i)); do
             options[i]=$( printf '%q' "${options[i]}" )
         done

         IFS=$'\n'
         COMPREPLY=( $( compgen -W "${options[*]}" -- "$cur" ) )
         IFS=$saveIFS
     fi
}

complete -F _ssh -o filenames ssh
$ . ./ssh_compspec

Then,

$ ssh -o <Tab><Tab>
ConnectTimeout=10                 nc -x host:port %h %p -X 5        nc -x
host:port %h %p -X connect

As we can see, "ProxyCommand" is missing.

OK. You asked for the completions to be treated as filenames. When
readline displays the possible completions for filenames, it doesn't
display the full pathname -- just the portion after the final slash.
The words with ProxyCommand= are trimmed to the portion after the
.../usr/bin/.
