Resolve the "Empty 'required by' message" issue

Fix #39

[larchunix]

Patch tested by upgrading from ffmpeg-1:2.8.1-2 to ffmpeg-1:2.8.1-3 and it worked fine in my case.

$ yaourt -Su
==> Package upgrade only (new release):
extra/ffmpeg   1:2.8.1-2 2 -> 3

==> New package :
extra/vid.stab 1.1-1     (required by ffmpeg)

==> Continue upgrade ? [Y/n]
...

The package vid.stab was correctly installed as a dependency

$ pacman -Qi vid.stab
Name           : vid.stab
...
Install Reason : Installed as a dependency for another package
...

[f2404]

Hmm, that's weird - I'm getting vid.stab "Explicitly installed" when running yaourt -Syu --aur. And I'm getting it "Installed as a dependency" when running yaourt -Syu.

[larchunix]

Really weird - I just tested with and without --aur and I got "Installed as a dependency" in both cases.

Hm, just tested and it seems that it works, with -Su and -Su --aur :

extra/vid.stab                            1.1-1                  (required by ffmpeg)

@Skunnyk ok then, will you merge it?
