There are two things which are not stringent in the flag naming. First the position of only varies between front and end, --onlydeps --buildpkgonly --fetchonly --getbinpkgonly --usepkgonly And second, the use of hyphens also varies --list-sets --searchdesc --binpkg-respect-use --buildpkg --buildpkgonly --complete-graph --config-root --fetchonly --fetch-all-uri --getbinpkg --getbinpkgonly --keep-going --load-average --root-deps --usepkgonly --with-bdeps
This is pretty low hanging fruit; I highly recommend providing a patch against both emerge, emergehelp, and the manpages. -A
It shouldn't sound like high priority, I just often mix --onlydeps and --fetchonly to --onlyfetch or so. I will take a look at it and provide a patch.
