* registered as a user dictionary word. If the word is actually modified, the IME needs to
* go back and replace the word that was committed with the amended version.

* Try to replace the string at the remembered position with the actual word being added.
*
* After the user validated the word being added, the IME has to replace the old version
* (which has been committed in the text view) with the amended version if it's different.
* This method tries to do that, but may fail because the IME is not yet ready to do so -
* for example, it is still waiting for the new string, or it is waiting to return to the text
* view in which the amendment should be made. In these cases, we should keep the data
* and wait until all conditions are met.
* This method returns true if the replacement has been successfully made and this data
* can be forgotten; it returns false if the replacement can't be made yet and we need to
* keep this until a later time.
* The IME knows about the actual word being added through a callback called by the
* user dictionary facility of the device. When this callback comes, the keyboard may still
* be connected to the edition dialog, or it may have already returned to the original text
* field. Replacement has to work in both cases.
* Accordingly, this method is called at two different points in time : upon getting the
* event that a new word was added to the user dictionary, and upon starting up in a
* new text field.
* @param connection The RichInputConnection through which to contact the editor.
* @param editorInfo Information pertaining to the editor we are currently in.
* @param currentCursorPosition The current cursor position, for checking purposes.
* @return true if the edit has been successfully made, false if we need to try again later
