Quoth perlfunc:

  system LIST
     [...] If there is only one scalar argument, the argument is checked
     for shell metacharacters, and if there are any, the entire argument
     is passed to the system’s command shell for parsing (this is
     "/bin/sh -c" on Unix platforms, but varies on other platforms).
     If there are no shell metacharacters in the argument, it is split
     into words and passed directly to "execvp", which is more efficient.
