[Spice-devel] [PATCH v3 05/11] Rephrase section about constants

[Christophe de Dinechin]

From: Christophe de Dinechin <dinechin at redhat.com>

The indent of the rephrasing is that:

- If you have a single constant, use const, e.g. (visible in debugger)
    const unsigned max_stuff = 42;

- If you have multiple constants, prefer enums over #define, as
    already suggested later in the guide:
    enum {
       A = 0,
       B = 42,
       C = -1
    }
