Bug#45192: libc0.2: path names with trailing slashes and rmdir,rename

[Marcus.Brinkmann@ruhr-uni-bochum.de]

Package: libc0.2
Version: N/A
Severity: normal

Hello,

the below program generates the following output:

hurd:/tests/dirslash# ./dirslash
rmdir foo1/ : Invalid argument
rename foo4 bar4/ : No such file or directory
rename foo5/ bar5 : Invalid argument
rename foo6/ bar6/ : No such file or directory

Only the output for foo4 and foo6 is POSIX conform. The two times were
Invalid Argument is returned are wrong (this makes `mv foo/ bar' copying all
files seperately, a pain with huge source trees).

Thanks,
Marcus
