here is one that is even more fun as works for any user:

[eb@socrates /tmp]$ ls -ld .
drwxrwxrwt    6 root     root         2048 Jan  4 20:33 .
[eb@socrates /tmp]$ cp /usr/share/man/man1/ls.1.gz .
[eb@socrates /tmp]$ ls -l ./ls.1.gz
-rw-r--r--    1 eb       eb           2271 Jan  4 20:34 ./ls.1.gz
[eb@socrates /tmp]$ man ./ls.1.gz
./ls.1.gz: No such file or directory
man: can't remove /tmp/zmanZNdPIa: No such file or directory
[eb@socrates /tmp]$ gunzip ls.1.gz
[eb@socrates /tmp]$ man ./ls.1
Reformatting ls.1, please wait...
...
[eb@socrates /tmp]$

this one is the wrapper's fault, it does a chdir() somewhere and then
gzip doesn't find the page (since it gets a relative pathname).
