This was broken during the refactor for "gomtree validate" in commit83c9fdb78b("refactor: prefactor for adding new subcommands"), resulting in any code that relied on our exit code to silently treat all errors as non-fatal. Our tests did not catch this due to a quirky POSIX-ism with regards to "! cmd" and "set -e" which is fixed in a follow-up patch.

This tool is written in likeness to the BSD MTREE(6), with notable additions

to support xattrs and interacting with tar archives.`
