[PATCH 1/2] bcachefs: split error messages of invalid compression into two lines

From: Integral
Date: Sun Apr 06 2025 - 11:29:44 EST


When an invalid compression type or level is passed as an argument
to `--compression`, two error messages are squashed into one line:

> bcachefs format --compression=lzo bcachefs-comp.img
invalid option: invalid compression typecompression: parse error

> bcachefs format --compression=lz4:16 bcachefs-comp.img
invalid option: invalid compression levelcompression: parse error

To resolve this issue, add a newline character at the end of the
first error message to separate them into two lines.
