Now that I told you.  However, “of course” *that* is questionable: within 
double-quotes, “\r” and “\n” are expanded as *string* escape sequences, 
before preg_split() sees them.  When in doubt, use either single-quotes or 
double-quotes with double-backslash.

I prefer to use double-backslash also with single-quotes in case someone 
decides in the future to support more escape sequences.  The resulting code 
style also is more consistent because with trailing backslash you *must* use 
double-backslash unless you want to escape the string delimiter: '\' is 
likely to become a syntax error (unterminated string literal); '\\' is not.
