From: Ronan Desplanques <desplanq...@adacore.com>
This patch removes an outdated reference to the concept of node
extensions in comments. It also slightly clarifies the documentation of
Atree.Relocate_Node.
gcc/ada/ChangeLog:
* atree.ads (New_Copy, Relocate_Node): Tweak documentation comments.
Tested on x86_64-pc-linux-gnu, committed on master.
