+Since commit 7eb8eecbb (ash: eval: Add assignment built-in support
+again) building BusyBox with the 'command' built-in disabled fails.
+
+parse_command_args() only needs to be called when the 'command'
+built-in is run.  Which it won't be if it's disabled.
+
+v2: Avoiding infinite loops is good, too.  Thanks, Harald van Dijk.
