emerge output is >>> /install/this/file even if it isn't, because of FEATURES="noman noinfo nodoc"
Those features automatically add /usr/share/{man,info,doc} respectively to INSTALL_MASK. If something is still being installed then it must not be in one of those locations. Can you confirm that?
No, the files do not get installed, it's just the output of emerge, which tells otherwise. Trivial, as I marked the bug. ;-)
It don't see how it could show in the output if it's not being installed. Can you post some example output for a specific package?
I had this issue in mind for a longer while and my testcase was "FEATURES=noinfo emerge app-doc/elisp-manual", but I fail to reproduce it with rc9 at least. Withdrawing, sorry for the noise, really. :(
