[yaourt] patch to remove a lost pacman lockfile

Question

I'm posting this for everyone who are lazy to remove a lost pacman lockfile.
I often misspell a package name or an option and interrupt pacman quickly before it syncs.
This ends up with pacman getting killed before it's lockfile can be removed.
I made a patch for yaourt to remove the lockfile if pacman is not running,
so I don't have to remove it manually every time.

Others have already said it, but it's worth saying again - fi you're going to use the AUR, learn how it works first before you start using any helper application. Your self-confessed uber-noobiness makes this an even more crucial requirement.
As meph mentioned, I too intended on having Yaourt only install AUR packages keeping pacman the primary in package installation.
The point is to know how to use the AUR without relying on a helper, because yaourt is more than a 'helper'. Something like 'cower' is much more of a helper in that you still have to take care of the main steps yourself. Using yaourt instead of pacman for -Syu doesn't change much, its using it as a 'pacman for the AUR' which can cause confusion. Which is as well the only reason to use it....
Durzo wrote:"learn how it works first" ...do you mean download each tarball PKGBUILD from the AUR separately, and then install with the "makepkg -is" command?
Yes. The fact that you even know that's what you have to do is already good (perhaps better than those who have right-away gone for yaourt).
There's no inherent 'negative' to yaourt (if you ignore the fact that it may not work following some pacman/libarchive upgrades) if you know how to live without it.
