Bug#534942: diversion-for-unknown-file: more false positives if output redirection is used

reopen 534942
thanks

Hi,

the fix recently applied for this bug causes some more false positives,
probably by treating a trailing digit of the file name as a file
descriptor being redirected: now I get reports like

> E: nvidia-glx-legacy-173xx: diversion-for-unknown-file usr/lib/libGL.so. preinst:88
> E: nvidia-glx-legacy-173xx: diversion-for-unknown-file usr/lib/libGL.so.1. preinst:89

for the following code:

> dpkg-divert --add --rename --package nvidia-glx-legacy-173xx --divert /usr/lib/nvidia/libGL.so.1.xlibmesa /usr/lib/libGL.so.1 > /dev/null
> dpkg-divert --add --rename --package nvidia-glx-legacy-173xx --divert /usr/lib/nvidia/libGL.so.1.2.xlibmesa /usr/lib/libGL.so.1.2 > /dev/null
