I have a function 'cs' that roughly looks like 'cd /some/prefix/$*',

Why not write a shell function that prefixes the right directory to
the word to be completed, runs compgen, and strips the prefix from the
generated list of completions?
Because "for some reason, non-trivial completions never seem to want to

Sigh. Ok, after trying for entirely too long, this seems to be working:
completeme() {
local i=0
while read l; do
COMPREPLY[$((++i))]="$l"
done < <(
cd /some/prefix
w="${COMP_WORDS[1]}"
if [ -n "$w" ]
then compgen -d "$w"
else compgen -d
fi
)
}
complete -F completeme cs
...and yet, seems entirely too difficult.
Why doesn't 'complete -C' work? Why does 'compgen -d ""' produce no
output? Shouldn't it produce the same output as 'compgen -d'?
