man: Commands aren't highlighted at all

[WhyNotHugo]

What steps will reproduce the bug?

I'm using batas a man pager:

$ echo $MANPAGER
bat-for-man

$ cat $(which bat-for-man )
#!/bin/sh
#
# man(1) can use a custom pager, but will exec `MANPAGER` as-is (e.g.: it won't
# pass it to a shell) so using arguments isn't possible.

col -bx < "$1" | bat --language man -p

What happens?

On man pages listing commands, commands themselves are not highlighted.

I'll use sway(5) as an example. With bat:

What did you expect to happen instead?

Without bat:

Here's another example where bat actually results in less highlighting that the man's default via less:

I'm still seeing the same behaviour after #2461.

Never mind, I didn't install the built-from-source files properly.
