The __bma_read_filters function is designed to take all arguments and join them with
| to create a grep pattern. Adding quotes around $@ would break this functionality
because:
__bma_read_filters "arg1 arg2" arg3
With unquoted $@:
• Gets word split into: arg1 arg2 arg3
• Results in: arg1|arg2|arg3
With quoted "$@":
• Would be passed as: "arg1 arg2" arg3
• Results in: "arg1 arg2"|arg3
The unquoted version is correct here since the function is intentionally using word
splitting to create individual grep pattern elements.
This is one of those cases where the normal "always quote your variables" rule has a
valid exception because word splitting is part of the intended behavior.
