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.
