this is kvim 6.2.14 ebuild - latest version in portage. as said, the mentioned item is missing in the edit menu. as a solution, the kvim developer m.marchand sent me a new menu.vim file - see http://svn.freenux.org/svn/kvim/trunk/runtime/menu.vim - after replacing /usr/share/vim/vim62 with the above, kvim would work ok. so I think the file should be installed by the ebuild ?
Please raise your voice in bug 56992, if necessary. I'll close this bug, if kvim gets hard masked.
