Hi,
I use vim as manpage with bash as following

export PAGER='/bin/bash -c "vim -MRn -c \"set buftype=nofile showtabline=0
ft=man ts=8 nomod nolist norelativenumber nonu noma\" -c \"normal L\" -c
\"nmap q :qa<CR>\"</dev/tty <(col -b)"'

export VISUAL='vim'

Until version 1.22.4 everything worked ok

With version 1.23.0 , manpages are showed with weird 1m and 0m at the
beginning and at the end of each line

Example on man groff
 01mName0m

01mSynopsis0m

With version 1.22.4 , everything works ok

I don't know if other user-cases are affected and what this bug technically
means
