manp cache dir

[metbril]

FYI

I was playing around with your manp script and replace the cache_dir with something more generic after taking note of this page:

https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

Your code:

dotfiles/bin/manp

Line 23 in 09aa03c

cache_dir=$DOTFILES/caches/manpdf

My improvement:

cache_dir=${XDG_CACHE_HOME:-$HOME/.cache}/$(basename "$0")
