On my system, manpage compression is disabled via PORTAGE_COMPRESS="". The new ecompress implementation in 2.3.50 creates empty files a la "/path/to/manpage.ecompress". Glancing at the code, there seems to be code which is supposed to delete those files, but it apparently doesn't work. The uncompressed original files aren't deleted though, so this is mostly a cosmetic issue.
