* Qual: Fix/extend language scripts, integrate in pre-commit
Updated scripts to comply with shellscript.
Integrated one in pre-commit that seems useful.
* Qual: Find duplicate lang keys
* Add line numbers (to allow annotation)
* Fix fixaltlanguages.sh and add to pre-commit
* Make historical language checks 'manual' in 'pre-commit'
# Qual: Ignore most shellcheck annotations, fix some
Most shellcheck annotations are ignored - this is to make sure that ci
can work for existing scripts.
Some fixes were applied.
pre-commit script was beautyfied by temporarily suppressing the IFS= expression on 2 lines.
