I think you are right. For a script hooking on htmlArea RTE link 
browser, the main hook key is changed. As a result, the RTE will also 
ignore hooks on the base class. I updated the ChangeLog (revision 3866).

I made this change when revising the DAM-RTE interface for links and 
images/media (soon to be committed to DAM SVN). With TYPO3 4.3, DAM will 
hook on the RTE rather than extend it (or rather than the RTE extending 
DAM)! These hooks are implementations of interface 
t3lib_browselinkshook. The DAM hooks instantiate the DAM browser which 
itself extends the same browse_links base class. In such context, one 
does not want hooks intended for the RTE to be reinvoked by the base 
class. Therefore, I ensured that the hook keys were specific to the RTE.

For TYPO3 4.3, since there is no central index of hooks, I will also 
update the htmlARea RTE API manual and add a section on hooks. However, 
this manual is on TER, but not in SVN.

Regards,
Stanislas
