I've been asked by Thomans Adam to indicate that the fvwm-convert-2.6 doesn't need to be stripped from the ebuilds for x11-wm/fvwm anymore because there is code for it now.
Created attachment 227869 [details, diff] Patch which removes fvwm-convert-2.6 removal Patch which removes fvwm-convert-2.6 removal which can be applied to fvwm-2.5.28.ebuild
Thanks for the patch! Assigning to maintainers.
