era_invalidate requires --metadata-snapshot with ignored arg

[sven-ola]

FYI - detected while transitioning from bookworm to trixie:

# C++ version 0.9.x ignores --metadata-snapshot flag (it does not hurt here either)
# Rust version 1.x requires --metadata-snapshot which in turn requires an
# ignored argument. To cope, we place /dev/era0-access twice at end of args
era_invalidate --written-since ${since:-1} --metadata-snapshot /dev/mapper/era0-access /dev/mapper/era0-access > ${BACKDIR}/${SSH_ACCT}.xml

As an annotation: "requires --metadata" means: without this flag, the Rust version never outputs any changed blocks i.e. list of changed blocks is always empty, which in turn leads to empty backups in my scenario.

Thank you for reporting this issue. The regression originated in v1.0.5 due to the clap dependency update. I’ll fix it shortly.
