bat as manpager

[ukiyocode]

This is on Linux Mint Willma, with bat installed through homebrew.
When I use the: MANPAGER="sh -c 'col -b | bat -p -l man'" option as described in readme i get weird color codes like: 1mSYNOPSIS0m, but when I simply use MANPAGER="bat -p -l man" everything works fine.

well mostly fine it seems to add [0m22m or [0m24m in front of left bracket (, but other than that formatting and colors are preserved

Additional context for why this is happening:

In summary, newer versions of groff changed to emit ANSI escape sequences by default, and col doesn't handle them properly. The following will work for both older and newer versions of groff:

export MANPAGER="sh -c 'sed -u -e \"s/\\x1B\[[0-9;]*m//g; s/.\\x08//g\" | bat -p -lman'"

That MANROFFOPT='-c' thing doesn't work for me, but eth-p's suggestion works perfectly, thanks :)

@eth-p worked for me too. FWIW, I'm on an RHEL8 system with my own terminfo created specifically for MS Terminal (undercurl support, etc).
