[PATCH 1/4] refresh_index: rename format variables

[Jeff King <peff@peff.net>]

When refreshing the index, for modified (or unmerged) files
we will print "needs update" (or "needs merge") for plumbing,
or a "diff --name-status"-ish line for porcelain.

The variables holding which type of message to show are
named after the plumbing messages. However, as we begin to
differentiate more cases at the porcelain level (with the
plumbing message stayin the same), that naming scheme will
become awkward.

Instead, name the variables after which case we found
(modified or unmerged), not what we will output.
