Currently using a space as a --debootstrapopts argument to separate its
arguments won't work anyway as debootstrap parses that as a non-option:

--debootstrapopts "--help -a=i386"

correctly gives

+ cdebootstrap --variant=buildd '--help -a=i386' sid . http://127.0.0.1/debian
cdebootstrap: unrecognized option `--help -a=i386'

and you are expected to pass cdebootstrap only options, as passing a valid
non-option will result in debootstrap having too much arguments:

--debootstrapopts testing

+ cdebootstrap --variant=buildd testing sid . http://127.0.0.1/debian
cdebootstrap: too much arguments

so yes, this bug is really about properly supporting spaces within
--debootstrapopts arguments

I'm not sure about the correct way to implement this, the most obvious is to
save IFS, use IFS=' ' during debootstrap invocation and restore IFS after that.

However, this is a proposed patch to the man page:

Although I prefer properly supporting arguments with spaces, as it is not going
to break anything. And mentioning "you can't use spaces" in the man page just
looks silly :)

my two cents,
