Seems like this should have a name pertaining to manifests if it has
manifest-specifics.

[Devlin, 2013/08/16 23:56:54]

It's in preparation for the more-generic call for either manifest or source
files (which is why there's also a file-type key in the call itself, even though
only manifest are here right now).  I'd put the rest in, but it seemed like this
patch was somewhat monstrous already, and didn't wanna overwhelm anyone more
than I already was.

Ok, it just seems incongruous to have this generic-sounding requestFileSource
and have the callback be GetManifestFileCallback.

+  void HandleRequestFileSource(const base::ListValue* args);
+
+  // Populate the results for a manifest file's content in response to the
+  // "requestFileSource" call. Highlight the part of the manifest which
+  // corresponds to the given |key| and |specific| locations.
+  void GetManifestFileCallback(base::DictionaryValue* dict,
+                               const std::string& key,
+                               const std::string& specific,
+                               std::string* contents);
+
+  // The profile with which this Handler is associated.
+  Profile* profile_;
+
+  DISALLOW_COPY_AND_ASSIGN(ExtensionErrorHandler);
+};
+
+}  // namespace extensions
+
+#endif  // CHROME_BROWSER_UI_WEBUI_EXTENSIONS_EXTENSION_ERROR_HANDLER_H_
