split /regex/ generates code with syntax errors in multiple cases

[snoopyjc]

split /regex/ generates code with syntax errors in multiple cases, for example:

($if1,$if2,$bytes) = split /\|/;

output code is missing the right paren. Also:

 ($r1,$i1) = split /:/,$ingress[0];

output code rhs is ONLY the right paren!
