Can I change the format of the Rich logging handler? (to work around broken terminal width detection)

[Hubro]

I'm in love with the Rich logging handler, but unfortunately I'm also addicted to hivemind and overmind, two awesome process managers for development.

When I run a process using the Rich logging handler in hivemind or overmind, Rich fails to detect the proper terminal width:

It assumes 100 columns and wraps log messages unnecessarily.

To work around this, is there any way I can reconfigure the rich handler to put the filename/linenumber on a different column and pretend it has infinite columns to work with? (i.e. never wrap)

You probably have a COLUMNS env var set.

I have manually set a value to $((COLUMNS-20)) to work around this issue. This works with hivemind, but not overmind. It's not perfect though, since the value doesn't update when I resize the terminal.

If I unset it (unset COLUMNS), Rich seems to default to 80 rather than detect the actual terminal width, so something is definitely wrong. I printed the value of os.environ["COLUMNS"] in Python and it's empty.
