Bug#3275: dpkg --no-act leaves control info in /tmp

[eichin@kitten.gen.ma.us (Mark W. Eichin)]

Package: dpkg
Version: 1.2.3elf

Having just done a "dpkg --no-act -GORBiE /debian" I now have 497
directories in /tmp, of the form /tmp/14417??? (presumably pid based.)
They contain control and pre/post/inst/rm files, and occupy nearly
2M... presumably dpkg is turning off one too many actions with --no-act,
namely the cleanup step.

In conjunction with
 grep 'to replace' gorbie-log  | awk '{ print $6 }' | sed s/\)// > gorbie-new
it is actually quite useful, and lets me pick and choose what I update
(particularly important on a running system...)

Thanks.
