g:pencil#textwidth setting not applied

Dist: Voidlinux
Vim 8.1, Included patches: 1-2402

Setting g:pencil#textwidth followed by autocmd for pencil#init() does not apply the expected textwidth. (Using Hardpencil).

Workaround done is

    autocmd FileType <ft> call pencil#init() | setlocal textwidth=<width>

Setting textwidth in pencil#init() call does not work either.
