I've reported this upstream.  I also agree with Enrico's suggestion of
using . instead of a quoted space, since that is the regex character that
will match a space:

updatedb --prunepaths='/cygdrive/c/WINDOWS /cygdrive/e /cygdrive/d
/cygdrive/z cygdrive/y /proc /cygdrive/c/System.Volume.Information
/usr /var
/cygdrive/c/Documents.and.Settings/furashg/Local.Settings/Temporary.Internet.Files
/usr/bin /cygdrive/c/System.Volume.Information /c/cygwin'

Perhaps that was in distro-modified versions.  I just included updatedb as
it is upstream, plus a single patch to recognize that on cygwin, the
filesystem recognition code doesn't work very well.

I agree that directory name lists should look like a PATH, and not be
space separated, but we will see what the upstream maintainer thinks.
