I haven't tested it, but it should work (and I'm confident you tested it ;) )
Anyway, using find, seems a hack to me. While find(1) is always present in
Debian systems (because findutils is a Priority: required package), we are also
upstream for bash-completion, and I have no idea whether find will be *always*
present in any Linux/Hurd/BSD distribution having bash (and, thus, able to have
bash-completion as well).

I'll commit the code, but please be warned that it might be removed in future,
if !Linux (or !Debian) users will complain :)

Thanks the good job,
David (I admit I haven't looked at the code since my last mail... :p)
