Pass only single commands through su wrapper
It is a healthy coding practice to keep each argument separate when
executing system calls, i.e. quote each variable separately instead of
relying on whitespace to indicate argument separation.
Quoting shell-inside-shell is tricky to do right, and gets trickier when
more than a single command is wrapped together.
This patch simplifies convoluted shell calls to contain only one command
each.
Example:
before: bash -c ". .../common; process_authorized_user_ids -"
after: bash -c ".../common process_authorized_user_ids -"
