I installed app-vim/ant_menu-0.5.7.1 and since that time, after quitting from vim my colors in xterm are screwed (actually bash). Notably, my prompt string is in blue instead of black. Unmerging the package restores the old behavior (that is if in a new xterm I run vim to edit a file, ':wq' to quit it and upon I return back to the bash inside my xterm I still have unchanged colors, notably the prompt string).
