Arch Linux

Description:

When updating all packages, including `man-pages`, pacman will fail because file `/usr/share/man/man3/explicit_bzero.3.gz` is already exist in filesystem.

Additional info:

Current installed version,

* man-pages 4.09-1
* libbsd 0.8.3-1

Steps to reproduce:

* Enable testing repo
* Run pacman update `pacman -Syu man-pages`

It will output something like these,

```
master ms 1 % sudo pacman -S man-pages

Looking at the owner of confict file,

```
master ms 0 % pacman -Qo /usr/share/man/man3/explicit_bzero.3.gz
/usr/share/man/man3/explicit_bzero.3.gz is owned by libbsd 0.8.3-1
```
