[pacman-dev] [PATCH v2] Provide a better guess about who the packager is.

[Kieran Colford]

The system usually has enough information in various places to guess
the name and email of the person running the makepkg script.  We can
use this to make the defaults more intelligent.  This particular
implemenation should provide relatively good guess that's compatible
with other programs (i.e. git).
