Install only local helpfiles with names of approximately the same length
(so that tabs after the names will line up) and, if more lining up is
desired, with first lines rigidly adhering to a common format?
Or, on Unix only, install your additional helpfiles in some directory
where Vim doesn't look, and place softlinks to them, with softlink names
of "approximately the same length" as said above, in $VIM/vimfiles/doc/
and/or ~/.vim/doc ? (Not sure if this would work.)
IOW, I don't think the game is worth the candle, but YMMV.
Best regards,
Tony.
