Typically with pref names and constants I've noticed that we put the
descriptions/comments in the .cc file; this is nice as it avoids having to look
at 2 files when searching for the constant's value and its associated
definition.

e.g. chrome/common/pref_names.cc, chrome_switches.cc

Done.

I didn't originally understand what was meant by "sans switch prefixes"; until I
realized you meant without "--" prefix.

I don't think this needs to be mentioned (chrome_switches.(cc|h) uses the same
scheme and doesn't mention it).

i mentioned it because it is a change from the old constants, which included "
--" (which i really didn't like). the point was to make it clear to those who
knew the old code that it's not broken now.
