Upstream prefers short debug messages (sometimes even limited to 80

characters), but any line length under 512 characters is just unsuitable

for effective debugging. (For example, config strings in HII routing,

logged by the platform driver "OvmfPkg/PlatformDxe" on DEBUG_VERBOSE

level, can be several hundred characters long.) 512 is an empirically good

value.
