pactree: Request for `-o' to Show Optional Dependencies.

[Ralph Corderoy]

Hi,

pacman-contrib 1.1.0-1.  Investigating
https://bugs.archlinux.org/task/50751, that I also suffered yesterday, I
see that graphviz doesn't have gtk2 as an optional dependency like the
bug report claims.  Perhaps that's historic, or it's a dependency of a
package that's directly optional.

`pactree graphviz' only shows the dependents.  It would be nice if there
was a `-o' option to treat optional dependencies as mandatory.  Perhaps
they could be indicated differently in the diagram.

Cheers, Ralph.
