Description:

LESS_TERMCAP variables are not correctly followed as of groff 1.23.0-1. Downgrading to groff 1.22.4-10 fixes it.

Steps to reproduce:

export LESS_TERMCAP_mb=$'\x1b[91m'
export LESS_TERMCAP_md=$'\x1b[38;5;74m'
export LESS_TERMCAP_me=$'\x1b[0m'
export LESS_TERMCAP_se=$'\x1b[0m'
export LESS_TERMCAP_so=$'\x1b[7m'
export LESS_TERMCAP_ue=$'\x1b[0m'
export LESS_TERMCAP_us=$'\x1b[04;38;5;146m'
man ls
This task depends upon

groff 1.23 drops the 'sgr' command [1][2], so the 'fix' in extra/groff package [3] no longer works.

A fix is `export GROFF_NO_SGR=1` or `export MANROFFOPT="-c"` - credits to [4]

Thanks, it worked! So the changes in the package can be dropped?

I believe so. Let's see what the package maintainer thinks.
