[Ian Jackson <ian@chiark.chu.cam.ac.uk>]

Package: debianutils
Version: 1.2-3

-chiark:d> cat >'cmd with spaces'
#!/bin/sh
echo "called cmd with spaces: $@"
-chiark:d> chmod +x './cmd with spaces' 
-chiark:d> './cmd with spaces' hi
called cmd with spaces: hi
-chiark:d> PATH=:$PATH 'cmd with spaces' hi
called cmd with spaces: hi
-chiark:d> PATH=:$PATH type -p 'cmd with spaces' 
./cmd with spaces
-chiark:d> PATH=:$PATH which 'cmd with spaces' 
-chiark:d> PATH=:$PATH which ls
/bin/ls
-chiark:d> ll

drwxrwsr-x  23 ian      ian          5120 Aug 31 19:52 ../
-rwxrwxr-x   1 ian      ian            44 Sep  1 16:27 cmd with spaces*
-chiark:d> echo $SHELL
/bin/bash
-chiark:d> 

This can be fixed by appropriate use of quoting, $@, and so on.
