"that we tried" what?

From the implementation, I think we mean "that we attempted to execute the
reporter tool."

Done.

+void RegisterSwReporterComponent(ComponentUpdateService* cus,
+                                 PrefService* prefs);
+
+// MaybeRegister will only register with the component updater if the preference
+// in |prefs| identifying that we tried has been set and the max number of
+// retries has not been reached yet.

The comment seems to imply that this will only do anything if
RegisterSwReporterComponent is called first? If so, make that explicit.

[MAD, 2014/06/16 13:03:55]

Done.

+void MaybeRegisterSwReporterComponent(ComponentUpdateService* cus,
+                                      PrefService* prefs);
+
+// Register user preferences related to the SwReporter component.
+void RegisterPrefsForSwReporterComponent(PrefRegistrySimple* registry);
