This can confuse the user who wants to figure out who actually requires the masked version. I suggest using the same information for the autounmask comment that is used for printing the dependency tree. Reproducible: Always

oh I forgot to mention: % emerge --version Portage 2.2.8-r1 (default/linux/amd64/13.0/no-multilib, gcc-4.7.3, glibc-2.17, 3.13.1-aufs x86_64)

This is absolutely still an issue. When a certain version of a dep "foo" is being forced, autounmask's comment's may blame ANY package which depends on "foo", not necessarily the one with the strict version dep. This is still a problem today on 2.2.10, and FYI the "reason" is correct when one uses --autounmask=n.

Currently, the best_match_to_list function is used to select the parent that will be displayed, and it does a poor job of selecting the most appropriate atom. The best_match_to_list function could be improved, but it will never be able to pick the correct atom in all cases. Therefore, we should probably have the autounmask infrastructure keep track of the specific atom(s) that trigger autounmask, make the depgraph._get_dep_chain method give preference to those atoms.
