[PATCH v2 3/7] var: format variable structure with C99 initializers

["brian m. carlson" <sandals@crustytoothpaste.net>]

From: "brian m. carlson" <bk2204@github.com>

Right now, we have only two items in our variable struct.  However, in
the future, we're going to add two more items.  To help keep our diffs
nice and tidy and make this structure easier to read, switch to use
C99-style initializers for our data.
